Specific Item Information: This model does not have ditch lights.

Model Information: InterMountain first announced this model in February 2014, followed by 5 additional announcements in April, June, August, November 2014 and August 2015, the last two being joint announcements for the HO and N models. Up to 52 different road names / paints have been announced, including high hood and snoot nose versions!

These models come with a brand new design that incurred significant delays. First batch has been announced to be shipping on the week of December 19th, 2016. In February 2017, Intermountain announced a second run of the just newly released 7 first road names, as well as two undecorated versions (US and Canada). 20 additional road names have been announced in February and April 2017, making it a total of 72 different road names.

Internally, these models are quite a departure from previous IMRC diesels. They do still seem to share a number of common parts with Atlas diesels of similar vintage (motor, trucks, etc), but the screwless (and wireless) chassis design is all-new. The fuel tank, motor saddle, and two plastic clips (one on the nose and one underneath the rear end of the PCB or decoder) serve to hold the whole assembly together ....

Note that ditch lights, for equipped models, will not alternate blinking as both are connected to the same light source.

DCC Information: This model is proposed factory-equipped with either a non-sound DCC decoder (models suffixed by "D") or a sound DCC decoder (models suffixed by "S"), both from ESU - LokSound Select Direct Micro or LokPilot Micro.
The factory-equipped DCC board (sound or non-sound) comes fully equipped with operational LEDs for rotary beacon and front/rear ditch lights. This makes it possible to later install those for locomotives not factory-equipped with them.

DCC manual for sound and non-sound versions can be downloaded from InterMountain Instructions Library - N Scale web page.
ESU LokSound file #93820 can be downloaded from IMRC DCC Assistance web page.
ESU are proposing a replacement board for this model in the case where you would like to add sound into a DC or DCC-silent version: the LokSound Select Direct Micro ref.73199.

Also accepts the following plug-in decoders (non-sound):

Prototype History: The EMD SD40-2 is a 3,000-horsepower (2,200 kW) C-C diesel-electric locomotive built by EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's Dash 2 series, competing against the GE U30C and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the 3,000-horsepower (2,200 kW) SD40-2 made it the best-selling model in EMD's history and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X.

Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, with production continuing for railroads in Canada until 1988, Mexico until February 1986, and Brazil until October 1989. As of 2013, nearly all built still remain in service.

The GMD SD40-2W is a Canadian-market version of the SD40-2 diesel-electric locomotive, built for the Canadian National Railway by the Diesel Division of General Motors of Canada Ltd. (formerly General Motors Diesel) of London, Ontario; 123 were constructed between May 1975 and December 1980. The major difference between the SD40-2W and a regular SD40-2 is the fitment of a wide-nose Canadian comfort cab, commonly denoted by adding a 'W' in the model name (although the GMD designation on the builders plates remained 'SD40-2').

The SD40-2 has seen service in Canada, Mexico, Brazil and Guinea. To suit export country specifications, General Motors designed the JT26CW-SS (British Rail Class 59) for Great Britain, the GT26CW-2 for Yugoslavia, South Korea, Iran, Morocco, Peru and Pakistan, while the GT26CU-2 went to Zimbabwe and Brazil. Various customizations led Algeria to receive their version of a SD40-2, known as GT26HCW-2.

SD40-2s are still quite usable nearly fifty years after the first SD40 was made, and many SD40s and locomotives from the pre-Dash-2 series (GP/SD 40s, 39s and 38s, and even some SD45s) have been updated to Dash-2 specifications, possibly including downgrading from 20-645E to 16-645E engines, including, certainly, Dash-2 electrical controls, although the pre-Dash-2 frames cannot accommodate the somewhat similar HT-C truck in the space allocated to the Flexicoil C truck (the frame is not long enough). Most SD40-2s which remain in service have by now been rebuilt "in-kind" for another 30 to 40 years of service, although a few (under 30) have been rebuilt to incorporate a 12-cylinder EFI-equipped 710G engine.

Road Name History: The Burlington Northern Railroad (reporting mark BN) was a United States railroad. It was a product of a March 2, 1970, merger of four major railroads - the Great Northern Railway, Northern Pacific Railway, Spokane, Portland and Seattle Railway and the Chicago, Burlington and Quincy Railroad - as well as a few small jointly owned subsidiaries owned by the four.

Burlington Northern operated between 1970 and 1996.

Its historical lineage begins in the earliest days of railroading with the chartering in 1848 of the Chicago and Aurora Railroad, a direct ancestor line of the Chicago, Burlington and Quincy Railroad, which lends Burlington to the names of various merger-produced successors.

Burlington Northern purchased the Atchison, Topeka and Santa Fe Railway on December 31, 1996 to form the Burlington Northern and Santa Fe Railway (later renamed BNSF Railway), which was owned by the Burlington Northern Santa Fe Corporation.*

Brand/Importer Information: InterMountain was founded in 1985 by Fred Brummet. They got started in the model railroad business by producing O-Scale model kits. They got started in the N Scale business almost a decade later when in 1994 they introduced the 40-23 reefer car in kit form. Later, in 1998, they started producing RTR (Ready-to-Run) models. By the early 2000s, InterMountain phased out kit production in favor of the RTR models.

The InterMountain Railway company is located at 1224 Boston Ave in Longmont, CO. They are a manufacturer of HO, N and Z scale model trains. They have produced kits as well as RTR (Ready-To-Run) models. Their N Scale products include locomotives as well as rolling stock. Their rolling stock lineup includes Boxcars, Hoppers, Tank Cars, Reefers, Gondolas, Stock Cars and Flatcars.

Their locomotive releases have primarily been diesel units, with the one major exception being their series of AC-12 Cab Forward steam locos. Their diesel lineup includes F3's, F7's, F9's, SD40's, SD45's and FT units. They are known for quality and detail. They also release their rolling stock in larger varieties of road numbers than most of the other manufacturers.
