N Scale Locomotives Enter The Sound Age

I've been modeling in N Scale for over sixteen years now. When I first started in N Scale, factory installed locomotives in N scale were a rarity. As time progressed factory installed decoders in diesels became more prevalent. Most of these decoders were not "top of the line" , but the modeler was still given the option of having a factory installed decoder in the locomotive, if the modeler chose not to install a decoder in the locomotive himself. I always installed decoders in all my locomotives when I had the option to do so.

When sound decoders became available, I installed Soundtraxx decoders in many of my steam locomotives (2003-2005). This changed in 2007, when I installed a ESU LOK-Sound decoder in a Kato Mikado. This sound decoder installation was published in the July-August 2007 issue of N Scale Magazine. From this point in time, I used ESU Select Lok-Sound Micro decoders in all future sound decoder installations in steam locomotives. I also replaced the Soundtraxx sound decoders I installed in many steam locomotives with ESU Lok-Sound Select Micro decoders. This was an expensive proposition but I wasn't happy with the motor functions of any of the Soundtraxx sound decoders. The ESU Lok-Sound Select Micro decoders motor functions are far supperior to the motor functions of the Sound Traxx decoders. The motor functions of the ESU ok-Sound decoders are equal to the motor function of the Lenz mini-silver decoders that I installed in steam locomotives and some diesels for years.

In 2005, the first sound decoder was factory installed in a Precision Craft Models (subsidiary of BLI) EMD E7. This was a major break-through in factory installed sound decoders in N Scale locomotives. I will discuss this sound decoder installation in a Precision Craft Model EMD E7 in another article. Subsequently BLI installed sound decoders (Paragon) in EMD E7's. EMD E6's, EMD 8's, EMD E9's, Alco PA's and Baldwin Centipedes. BLI also finally released a PRR 4-8-2 M1A and a PRR  4-8-2 M1B with a sound decoder factory installed. The sound emanating from the PRR 4-8-2's is exceptional and any of the above locomotives is worthy of a purchase by an N scale modeler.

Athearn was next in line to offer sound decoders in some of their diesels. The sound decoders used by Athearn were stripped down versions of Soundtraxx decoders.Athearn used these sound decoders in F45, FP45 and F59PHI diesels. While the operator was given many sound functions to control, fore the most part they were only basic sound functions.

For steam, Athearn released several models of the Athearn Challenger with MRC decoders that were factory installed. Athearn also released several models of the "Big Boy", again with MRC sound decoders installed in 2006. The sound in these steam locomotives was adequate, but the motor functions were suspect.Many DCC command stations had trouble reading the MRC sound decoders and as a result the MRC sound decoders were difficult to program.
Athearn later re-released both the "Challenger" and "Big Boy" with Soundtraxx sound decoders installed which was a big improvement over the MRC sound decoders (2010).

I purchased my Athearn "Challengers" and "Big Boys" from the first run that Athearn released. After this release Soundtraxx offered Soundtraxx decoders in the after market to replace the MRC sound decoders that were factory installed in the Athearn "Challengers" and "Big Boys". The resultant performance of both the "Challengers" and "Big Boys" with the Soundtraxx replacement sound decoders was remarkable and worth the extra cost in my opinion. At this pint in time, Athearn is planning to release new models of the "Challenger" and "Big Boy" in the next 12-18 months (2017-2018), and should be well received by N scale modelers.

In 2013 (approx.) Kato released the UP 4-8-4 FEF #4-8-4, a high powered steam locomotive that was DCC ready. Shortly after its release TCS a drop-in decoder for the FEF that didn't have to be hard-wired. Factory installed sound in this fabulous steamer would have been a big breakthrough in N scale sound from Kato. Believe it or not Kobo, a division of Kato installed ESU Lok-Sound Select Micro sound decoders in the UP 4-8-4 FEF #844 a short time later. At this point in time Kato is releasing another run of UP FEF #844 with ESU Lok-Sound Select Micro decoders factory installed, along with a run of a Union Pacific FEF3 #838 freight Version with an ESU Lok--Sound decoder installed.

In 2016 Kato released its first diesel with a sound decoder, the EMD SDP40F locomotive in Santa Fe and BNSF Maersk road names. Also to be released is the EMD SDP40F Type 1 Amtrak Phase 1 & 2 locomotives.

According to Kato "The EMD SDP40F was Amtrak's first, official, built to order locomotive after previously operating second hand equipment, such as E8's, F7's and even GG1's. Based on the framework of the SD40-2, the SDP40F was geared for speed, with a top operational velocity of 100 mph and a pair of steam generators to supply heat and hot water for the passenger trains it would pull, such as the ex-Santa Fe "El Capitan" and "Super Chief" (renamed the "Southwest Chief" or "Southwest Limited" in its combined state). The Phase II paint scheme replaced the painting and graphic design treatment that was originally used on the first batch of these delivered in 1973."

"After serving Amtrak, many of the venerable SDP40F diesels made their way into freight service for the Santa Fe where they continuned plying the rails for almost 15 additional years before their eventual retirement.
Coming along with their repurposing in freight service, these units were modified with a number of changes from their original Amtrak days -- the entire front porch area was gated in with safety railings, while two notches were introduced on the nose to allow more easy access to the front deck from the steps on the nose for maintenance purposes.
Kato will produce two different variations of the late-appearance freight SDP40F - the Santa Fe and the Maersk (BNSF) types. Each one carrying prototype-specific detailing that represents the individual unit styles."

• The first locomotive built specifically for Amtrak service.
• Like the prototype, the SDP40F is based off of the Kato smooth rulnlning SD40-2 Drive, making it a proven and reliable mechanical design that will be easily upgradable with a decoder for DCC operation.
• Coming in both the classic Phase I and Phase II paint schemes -- a perfect pairing for Amtrak "El

Bachmann first released a diesel with a Soundtraxx Sound Value decoder in 2012.The EMD N Scale DD40AX Centennial is one of the longest diesels in N scale.

 DCC-equipped for speed, direction and lighting
• dual-mode NMRA decoder
• operates on both analog and DCC layouts!
• precision can motor with flywheels
• 12 wheel drive
• finescale LED headlights (constant lighting)
• weathered air intakes and exhaust stacks

  Bachmann was next to release N scale steam with sound decoders. In 2014, Bachmann released the 2-8-4 "Berkshire" in three road names with sound decoders factory installed. However Bachmann used a Soundtraxx decoder that was basically stripped down in these steam locomotives. Although the sound is reasonably accurate, many of the sound functions are limited and the motor control of these steam locomotives are not on the same par with ESU Lok-Sound decoders. The details in these Bachmann steamers are outstanding and compare to the Bachmann Spectrum line of steam locomotives.

 "This DCC sound-equipped locomotive includes Sound Value SoundTraxx(R) steam package that includes authentic prototypical chuff, short and long whistles, bell, air pump, steam release, and blower
Precision motor, die-cast chassis, details and tender style per prototype, machined-brass flywheel, metal handrails and stanchions, directional LED headlight and tender backup light, die-cast marker lights, see-through underframe, metal wheels, and E-Z Mate(R) knuckle couplers." (From Model Rail Stuff)

I have four of these "Berkshires"; two Nickel Plate Road  2-8-4's and two Chesapeake and Ohio 2-8-4's. They all run and sound beautifully. I was able to program the CV's so these steamers start up slowly (one tie at a time) which is a problem with these steamers. The other issue I have with the Bachmann 2-8-4 "Berkshire" is that once the locomotive is on the track, even though you don't call up it's number, the sound decoder starts to send out all the start up sounds. I haven't been able to figure out how to prevent this from happening. With ESU Lok-Sound decoders this start up feature can be turned off until the locomotive number is called up by the DCC command station.

In 2015, Bachmann continued its release of N Scale steam locomotives with sound, when the Pennsylvania  4-6-2 K-4 was released with four road numbers. These locomotives are beautifully detailed and the sound is magnificent. Again Bachmann used the Soundtraxx Sound Value decoder. However with this decoder, you are able to turn off the startup features of the locomotive if the locomotive number isn't called up. I purchased all four road numbers and each locomotive is exquisite and performs beautifully. There are two pre-war versions and two post-war versions.

According to Bachmann, " The Pennsylvania Railroad's K4s 4-6-2 "Pacific" (425 built 1914-1928, PRR Altoona, Baldwin) was their premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957. It is recognized as the State Steam Locomotive of Pennsylvania. On December 18, 1987, Pennsylvania Governor Robert P. Casey signed into law House Bill No. 1211 naming the PRR K4 as the "official" state locomotive, according that title to both K4 survivors, 1361 and 3750."

Features The K4 4-6-2 is now available in Bachmann's line of N scale DCC sound-equipped locomotives with our Sound Value SoundTraxx steam package that includes authentic prototypical chuff, short and long whistles, bell, air pump, steam release, and blower - all in 16-bit polyphonic sound. This finescale engine also features a die-cast chassis, precision motor, and prototypical detailing. The Pre-War K4 models, based on a World War I-era model, feature distinctive "chicken coop" slat pilots, while the Post-War versions are equipped with modern pilots.                                                                                                                                                    Bachmann was very active in 2015 and released an EMD SD-45 with a Soundtraxx sound decoder factory installed. According to Bachmann "The "special duty" SD45, a 3600-HP prime mover with a V-20 engine and six-axle trucks for superior tractive effort, embodied the latest and greatest technological advances of its day." Features This DCC sound-equipped EMD SD45 Diesel includes our Sound Value SoundTraxx diesel sound package with prototypical prime mover, 3 air horns, and bell-all in polyphonic 16-bit sound Performs best on 11.25" radius curves or greater                                                                               I purchased two of these diesels and wasn't particularly happy with the way the Soundtraxx Sound Value decoders performed. Also the detail of the Bachmann EMD SD-45's was just adequate.  Five road names were released; Erie-Lackawanna, Santa Fe, Pennsylvania Railroad, Northern Pacific and Rio Grande. I purchased a Santa Fe unit and a Rio Grande unit. Atlas was next in line to release a diesel with an ESU Lok-Sound Select Micro decoder in 2015. The S-2 diesel switcher is a neat small locomotive. I purchased 2 Santa Fe S-2 units and they perform extremely well. The detailing is crisp and the sound from the ESU Lok-Sound decoder is outstanding. I have a third ATSF S-2 which still hasn't been released as Atlas has released these units in small batches. Atlas has issued the S-2's in a multitude of road names and I can highly recommend the purchase of the small switcher with sound. You won't be disappointed. The S-2 was "built by the American Locomotive Company (Alco). The low-hood S-2 was introduced in 1940 to replace Alco's earlier high-hood switchers. The 1000 horsepower S-2 was a turbocharged version of the S-1. There were 1,502 S-2s sold to North American Railroads. The versatility of the S-2s was evidenced by their service on mainline, shortline and industrial railroads.  Features Scaled from actual prototype measurements Option for horizontal or vertical radiator shutters Fine scale handrails Separately-applied coupler cut levers, air hoses, piping, etc. Directional LED lighting (includes cab rear headlight) Die-cast hood and chassis for improved pulling performance Digital-ready chassis Dual-flywheels for maximum performance at all speeds Factory-equipped with Accurail's AccuMate(R) knuckle couplers Exceptional painting and printing DCC Operation Features: Support for all DCC-programming modes Flexible mapping of function keys F0 to F28 A total of 4 DCC function outputs are available Follows all NMRA DCC standards and recommended practices Sound Functionality Features: Over 20 sound effects are available, including engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes and more There are 16 user-selectable horns, 2 user-selectable bells, and 2 user-selectable synchronized brake squeals Manual and Automatic Notching modes with the ability to change modes "on the fly" are provided for true realism. Rapido started to release N scale locomotives in N Scale again in 2012. In 2013 Rapido released the GMD-1 locomotives. All road names were Canadian and this small diesel switcher is one fine locomotive. " Rapido Trains Inc. and Montreal Locomotive Works are delighted to announce the N scale GMD-1 locomotive. The GMD-1 was built between 1958 and 1960 by General Motors of London. The locomotive is an extended 1200 HP roadswitcher, equally at home on the branchline, on the mainline, and in the yard. We are pleased to be offering this locomotive in two distinct versions: the original 1000-series and the later rebuilt 1600-series. The 1000-series GMD-1 features A-1-A trucks to distribute its 120 tons over six axles and allow travel on light rail branches in the Prairies. The 1000-series GMD-1 was intended mainly for freight service, with its 65 MPH gearing and lack of a steam generator or pass-through steam lines. However, they could be used with Steam Generator Cars as their cabs were equipped with steam generator controls and blowdown buttons. All 78 1000-series GMD-1 locomotives were delivered between 1958 and 1960. In 1988 CN rebuilt 15 more GMD-1 locomotives for continued branchline use on the Prairies. This was a major rebuild performed by CN's Pointe St-Charles shops in Montreal. The batteries were removed from the short hood and replaced with a chemical toilet and access door and the batteries were moved outboard beside the short hood. The units received anticlimbers, ditch light brackets, straight exhaust stacks and several mechanical upgrades. The cabs were re-oriented to run short hood forward, and interior facilities were improved - they now had a fridge! The 1600-series units were called GMD-1A and received the class designation GR-612A. Rapido Trains Inc. and Montreal Locomotive Works are delighted to announce the N scale GMD-1 locomotive.

I purchased two GMD-1 switchers; a Northern Alberta Railroads #302 and a Canadian National RR (Green scheme). Both of these diesels are finely detailed and run beautifully. Rapido also released a Canadian National RR with stripes with various configurations.  Features SOUND MODEL N Scale DC/DCC dual mode (ESU factory decoder equipped!) or equipped with an ESU DC/DCC/SOUND LokSound decoder Dummy plug included with silent models for optional straight DC operation 5-pole, skew-wound motor with excellent slow-speed performance Accurate dimensions from GMD blueprints and field measurements Heavy, die-cast chassis for great pulling power Accurate 1000-series (6-axle) and 1600-series (rebuilt GMD-1A) variations A-1-A trucks with prototypically sized 40" and 33" wheels Full cab interior oriented the correct way (long hood forward for CN 1000-series, short hood forward for NAR and 1600-series) Body-mounted Micro-Trains couplers Up to six road numbers plus unnumbered for each paint scheme True GMD-1 sounds recorded from #1118 (formerly #1018) on the Alberta Prairie Railway BE SURE TO READ THE INSTRUCTIONS BEFORE USING!

The EMD FL9's took over from the PA's in the very early 1970's. " The EMD FL9 has secured a rightful place in North American railroad history. These dual-power locomotives were designed to operate on both diesel-electric and on pure electric power so that they could haul the New Haven Railroad’s passenger trains in and out of New York City’s Grand Central Terminal without the need for an engine change.  Built between 1955 and 1960, many of the fleet continued in regular revenue service for nearly fifty years on both long haul and commuter trains. While the last revenue commuter run occurred in 2009, two units remain in regular revenue service today on the Maine Eastern between Brunswick and Rockland Maine. Several others have been preserved and are in use on tourist railroads in both the US and Canada." The EMD FL9's were leased in the following road names: New Haven (various configurations), Penn Central, MTA  (1979-1983), Metro North (1979-1983), Amtrak (various configurations) and Undecorated versions. Many modelers who purchased the EMD Rapido FL9 state that its is nicely detailed and runs extremely well. The backup light is  functional as well. One must be careful not too pull out the trucks from the frame as there is difficulty repositioning the truck contacts on the underlying metal contact strips as the strips can be easily bent out of shape.  Features Correct details Separate grab irons Road-number and era-specific details applied at the factory Correct fuel and water tanks, cooling coils, and other details! Full underframe details Operational headlight and back-up lights Full cab interior Sound-equipped DCC model with an ESU LokSound sound decoder Authentic sounds including Hancock air whistle (where appropriate) Will operate smoothly on DC and DCC layouts Rapido’s proven 5-pole, skew-wound motor and silky-smooth drive system Micro-Trains couplers mounted at the correct height  MRC formerly Model Power has also released new 4-6-2 "Pacifics" and 2-8-2 "Mikado's" with sound using MRC sound decoders. Both the 4-6-2 "Pacifics" and 2-8-2 "Mikado's" were released in various road names. I purchased two MRC 4-6-2 "Pacifics" ,  a UP 4-6-2 and a Southern "Crescent" 4-6-2. Both performed adequately and the sound was pretty good for a MRC sound decoder. The one thing that improved immensely was the pulling power of this steamer. 25-30 cars is the norm for the steamer on level track, which was a big improvement over the pevious rins of MP 4-6-2's which could barely pull itself up a 2% grade. However, the wiper system on the locomotive and tender is basically still the same, 1970's technology. The performance of the 4-6-2 would be greatly enhanced if you used a Kato Mikado tender or a Bachmann Spectrum tender where all the tender wheels are "live". I used the above technique on an Undecorated MRC 2-8-2 "Mikado" that I purchased. This steamer would barely run six -twelve inches before it would shut down. The tender wipers were all bent out of shape upon close inspection. I guess MRC never cleared up the quality control issues that MP had. So, to make a long story short, I used an extra long Spectrum long tender I had, and completely rewired the locomotive and MRC sound decoder in the Spectrum tender. I also replaced the MRC factory installed speaker with a Zimo sugar cube speaker. I used a Kato Mikado draw bar to attach the tender to the MRC locomotive. Now this steamer runs and sounds beautifully and pull 35-40 cars on level track. Due to the erratic performances of these MRC steamers due to their tender issues, I doubt I'll be buying any new MRC steamers until MRC changes the design of the wiper systems on their locomotive and tenders. " Following the federal takeover of the nation's railroads in late 1917, the United States Railroad Administration (USRA) began developing standardized locomotives (a radical idea at the time) to create a national pool of engines that could be operated anywhere they were needed. Common parts simplified construction and repair. Among these designs was a heavy 2-8-2 for roads where track and bridges would support an engine slightly larger than a light Mikado. While 233 were built under USRA control, the design proved to be popular and over 900 copies were built with minor variations. Some 27 different railroads owned heavy "Mikes," many of which were later upgraded and rebuilt, and served until the end of steam."   Features - Beautifully Packaged in a Jewelry Style Plastic Chest! - Die-Cast Metal Boiler, Cylinders, & Frame - Knuckle Coupler Equipped - NEW Tender Pick-ups - NEW Pilot Truck Pick-up - NEW Improved Driver Wiper Pick-ups - Traction-Tire Equipped for Extra Pulling Power - NEW Notched Driver Axle - NEW Golden White LED Lighting - Precision Brass Fly-Wheel and Worm Gear - Superior Painting and Authentic Schemes - Separately Applied Details - Road Name Specific Details (Trailing Truck/Tender) Industry Leading MRC DCC & SOUND - Dual Mode -- Operates in DC & DCC - 16 Bit Sound -- Volume Control - Back EMF Load Control - Pilot Light Operation - Auto Brake sound Feature w/Brake Activation - Choose from 17 Whistles w/Individual Volume & Rate Control - Choose from 8 Bells w/Individual Volume & Rate Control - Choose from 10 Chuffs w/Individual Volume & Rate Control - Prototypical Non-Articulated Sound - Individual Sounds VOLUME CONTROL FOR ALL THE FOLLOWING AND MORE!... - Brake Squeal - Air Release - Blower Hiss - Water Injector - Coupling - Water Filling - Rail Clack  Now onto Intermountain.
