Model Information: Atlas introduced this model in 1986. It was originally produced by Kato for Atlas under contract. The Kato version shares a chassis with Kato's RS-3 model but some of the internal components differ, primarily in the worm assembly. Atlas ceased importing this model in the 1990s and later, in 2006, designed their own version which was produced in China. This new version (2006+) is properly DCC-Ready and accepts a drop-in decoder. It also features a skew-wound motor with all eight wheels involved with electrical pickup and drive (no traction tires). The Chinese version features body-mounted AccuMate couplers whereas the Kato version have truck-mounted couplers. This version also has Golden White LEDs, separated handrails and side sill and a prototypical wheelbase. The Kato wheelbase is off due to the common chassis shared with the RS-3.

See a video of these engines on our YouTube Channel

DCC Information: Models produced from 2006 are DCC Ready or Dual-Model Decoder Equipped. They accept the following drop-in decoders:
- Digitrax DN163A0: 1 Amp N Scale Mobile Decoder for Atlas N-Scale GP40-2, U25B, SD35, Trainmaster, B23-7 and others
- TCS AMD4 (Installation for Atlas RS-11)
- NCE N12A0: Plug and play decoder for N-Scale Atlas GP40-2, U25B, U23B, B23-7, 30-7, 36-7, GP38, SD25, TRAINMASTER, etc.
- MRC 1812: N-Scale Sound Decoder for most Atlas short/medium 4-axle locos (selection of 4 prime movers - might not be prototypical for this model however)

Earlier DCC factory-equipped versions were fitted with Lenz LE063XF decoders, whereas most recent versions are fitted with NCE N12A0 decoders. The Atlas version of these decoders will respond to manufacturer's address "127" (CV8) i.e. "Atlas Model Railroad Products", though being identical to their original manufacturer's specification.

Prototype History:
The ALCO RS-11 is a diesel-electric locomotive of the road switcher type rated at 1,800 hp (1.34 MW), that rode on two-axle trucks, having a B-B wheel arrangement.

The first three RS-11s were produced by ALCO in February 1956 as a demonstrator set. This locomotive, classified by ALCO as model DL-701, was their first high-horsepower road switcher,[1] intended to be a replacement for the very popular RS-3 road switcher. Featuring a V-12, 1,800 hp (1,300 kW) 251B diesel engine, the RS-11 was ALCO's answer to EMD's very successful GP9. The turbocharged RS-11 accelerated faster, had a higher tractive effort rating and typically used less fuel than the competition. It was also quite versatile and could be found in heavy haul freight as well as passenger service. It was produced in high-nose and low-nose versions. Montreal Locomotive Works built identical units.

Road Name History:
The NTRAK organization was founded in 1973. Its mission is to provide a set of specifications for N Scale modular layouts.

NTRAK modules are designed to bring model railroading to the public at conventions, exhibits, and shopping malls. In the past a person wanting to see model trains in operation had to seek out a club or home layout that was open to the public. These layouts were often designed for the convenience of the owners and operators, and not for public viewing. The modular layouts have the flexibility to be fitted into many different size and shape areas. They offer close up viewing and maximum train action. Long trains passing each other are always attention getters and are a feature of the NTRAK layouts. While designed for large public display layouts, the NTRAK modules are being used for home layouts and for club layouts as well. For the modeler, the NTRAK modules offer a number of advantages over a fixed layout. We are such a mobile society and the modules make it very easy to move a layout from one home to the next without destroying all the work that went into it. Our smaller homes, apartments, and mobile homes all lend themselves to N scale layouts. Persons who want to run longer trains have the opportunity to take a module to one of the many NTRAK meets during the year and to be part of a large layout. There they can run their longer trains and meet other N scale modelers.

Brand/Importer Information:
Ak-Sar-Ben Hobby Co
Information on AkSarBen Hobby and their history is sketchy at best. Of course, AkSarBen is Nebraska spelled backwards so one might assume that they got their start in the Husker state. The most recent evidence of their existence, however, was in the 2010 Model Retailer Hobby Industry Directory listing them in Jacksboro, TN. The phone number listed is disconnected, so, who knows for sure? What is known is that AkSarBen Hobbies was owned by Allen Miller and got their start in the 1980's producing very high quality custom, limited edition HO and N Scale products. They probably have left the model train business for more than 20 years ago.
