Model Information: Atlas introduced the SD60 in 1998. The SD50 and SD60M followed in 1999. In 2002 they revised the SD60M and SD50. In 2005, Atlas revised the SD60. All three models (SD60, SD60M and SD50) share the same mechanism and differ only in shell detailing. These models also come with uninstalled detail parts such as snow-plow and winterization hatches. These details must be installed by the owner.
The revised versions all carry typical post-2000 mechanisms. Therefore, we see features such as dial flywheels, all-wheel pickup and drive, blackened metal wheels, bi-directional lighting, a split-frame DCC-Ready chassis and easily-swappable body-mount couplers. The revised version feature Atlas' slow-speed motor, golden white LEDs and nicely painted two-tone handrails. Yes, they run very nicely.
DCC Information: The revised version of this model is DCC ready. It is available either in DC or DCC-equipped, with Lenz LE062XF for earlier runs, and with NCE N12A1 for more recent ones.
Models accept the following after market plug-in decoders:
- Digitrax DN163A1: 1 Amp N Scale Mobile Decoder for Atlas N-Scale SD60, SD60M, SD50 and others.
- TCS ALD4: Four Function decoder, for Atlas Long length Drop-in.
- NCE N12A1: Plug and play decoder for N-Scale Atlas SD50, SD60M, SD60.
The development of the 16-cylinder EMD 50 and 60 series locomotives in the late 1970s and early 1980s was spurred by the introduction of 3,600 horsepower (2,700 kW) 16-cylinder GE B36-7 (B-B) and GE C36-7 (C-C) locomotives by EMD's main competitor General Electric. EMD previously manufactured the 3,600 hp (2,700 kW) 20-cylinder SD45 and SD45-2 locomotives, but they had a reputation for high fuel consumption. In 1980, the SD50 model was added to the EMD Catalog. However, the SD50's electrical reliability was poor and, similarly, the 3,500 horsepower (2,600 kW) 16-645F engine had poor mechanical reliability, both believed to be largely due to excessive vibration from the 950 maximum rpm of the 645F prime mover. It was time to develop a replacement for the venerable 645 engine which, in its earlier 16-645E form, had proved to be exceptionally reliable. EMD therefore quickly commenced development of the SD60 series, which would eliminate the weaknesses of the SD50. The lessons learned in developing the 645F crankcase and crankshaft (for the earlier 20-645E, and the then-current 16-645F) were incorporated in the replacement, the 710G, first employed in the SD60. Although the carbody and frame are nearly indistinguishable from the earlier SD50, the SD60 featured the new 16-cylinder EMD 710G3A prime mover, AR-11 traction alternator, D-87 traction motors and a microprocessor-based control system that governed various electrical systems within the locomotive (e.g., wheel slip and transition).
Road Name History:
GATX Corporation is divided into four business segments: Rail North America, Rail International, American Steamship Company (ASC), and Portfolio Management. Portfolio Management consists largely of the corporation's non-rail and non-Great Lakes assets.
GATX is one of several major North American rail operating lessors, and measured by fleet size, ranks as number two in this market behind GE Rail Services. Other major North American rail operating lessors include CIT, First Union, Union Tank Car Company, Trinity Industries Leasing, ARL, and Helm Financial.
GATX derives its name from its primary reporting mark for its North American railcars, "GATX". The mark itself was derived from GATX's prior corporate name, "General American Transportation". Since all non-railroad owners of railcars must append an "X" to the end of their mark, GAT became GATX. GATX mainly applies the GATX mark to tank cars, although the mark has been used in other examples such as with hoppers; GATX's primary freightcar marks are GACX (for general-service freight cars), GGPX (for coal cars), GIMX (for intermodal cars), GPLX (for plastic pellet cars), GMTX and LLPX (for locomotives), and GPFX (for pressure-differential cars). GATX also owns a number of other marks, including GABX, GAEX, GFSX, GOHX, GSCX, IPSX, and TRIX. Many GATX cars carry a large "GATX" logo in the upper right-hand corner of the car regardless of the reporting mark they carry; this logo is applied for marketing reasons and does not have any operational significance.
The General American Transportation Corporation became GATX Rail Corporation, a unit of the GATX Corporation, on January 1, 2000.
GATX engages in both full-service and net leasing of railcars. In a full-service lease, a GATX-owned mark is applied to the car, and GATX maintains the railcar and pays for any required property insurance and property taxes. In a net lease, the lessee applies its mark to the car, and the lessee pays for any required property insurance and property taxes. Often, on a net-leased car, there is no evidence of GATX ownership, although some net lease cars carry a GATX logo.
The most common type of car in the GATX North American fleet is the tank car; other major car types include covered hoppers, open-top hoppers, and gondolas. GATX invests in nearly every type of railcar operated in North America. In Europe, tank cars also make up GATX's largest fleet, but unlike in North America, GATX's European fleet includes substantial quantities of intermodal cars which are owned in a GATX joint venture called AAE Cargo. In contrast, GATX's North American intermodal car fleet is relatively small. This is true of most North American operating lessors; historically the bulk of the industry's intermodal investment has been made by TTX Corporation, which is jointly owned by North America's Class I railroads.
In those days, railroad modelers had to assemble and build everything from scratch. Steve Jr. created a "switch kit" which sold so well, that the entire family worked on them in the basement at night, while doing business as usual in the machine shop during the day.
Subsequently, Steve Jr. engineered the stapling of rail to fiber track, along with inventing the first practical rail joiner and pre-assembled turnouts and flexible track. All of these products, and more, helped to popularize model railroading and assisted in the creation of a mass-market hobby. The budding entrepreneur quickly outgrew the limitations of a basement and small garage operation. Realizing they could actually make a living selling track and related products, Steve and his father had the first factory built in Hillside, New Jersey at 413 Florence Avenue in 1947. On September 30, 1949, the Atlas Tool Company was officially incorporated as a New Jersey company.
In 1985, Steve was honored posthumously for his inventions by the Model Railroad Industry Association and was inducted into the Model Railroad Industry Hall of Fame in Baltimore, Maryland. In addition, Steve was nominated and entered into the National Model Railroad Association Pioneers of Model Railroading in 1995.
In the early 1990s, the Atlas Tool Company changed its name to Atlas Model Railroad Company, Inc.
