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.

Prototype History: 
The SD50 was produced in response to increasingly tough competition from GE Transportation Systems, whose Dash 7 line was proving quite successful with railroads. While EMD's SD40-2 was a reliable and trusted product, GE's line included locomotives up to 3,600 hp (2,685 kW) with more modern technology, as well as very competitive finance and maintenance deals. EMD responded throughout the SD50 program by offering discounts on large orders.
GM-EMD had previously produced 3,600 hp (2,685 kW) locomotives, the SD45 and later SD45-2, but these used huge, 20-cylinder engines with high fuel consumption, and had reliability problems when first introduced. Demand for the 45 series dropped sharply after the 1970s fuel crisis. The SD50 used an updated version of the V16 645 used in the SD40-2, uprated to 3,500 hp (2,600 kW)- and later 3,600 hp (2,685 kW) - at 950 rpm from 3,000 hp (2,240 kW) at 900 rpm. This proved to be a step too far; the 50 series models were plagued by engine and electrical system problems which harmed both sales and the reputation of EMD.

Road Name History: 
The Seaboard Coast Line Railroad (reporting mark SCL) is a former Class I railroad company operating in the Southeastern United States beginning in 1967. Its passenger operations were taken over by Amtrak in 1971. Eventually the railroad was merged with its affiliate lines to create the Seaboard System in 1983.
At the end of 1970 SCL operated 9230 miles of railroad, not including A&WP-Clinchfield-CN&L-GM-Georgia-L&N-Carrollton; that year it reported 31293 million ton-miles of revenue freight and 512 million passenger-miles.
The Seaboard Coast Line emerged on July 1, 1967, following the merger of the Seaboard Air Line Railroad with the Atlantic Coast Line Railroad. The combined system totaled 9,809 miles (15,786 km), the eighth largest in the United States at the time. The railroad had $1.2 billion in assets and revenue with a 54% market share of rail service in the Southeast, facing competition primarily from the Southern.
On November 1, 1980, CSX Corporation was created as a holding company for the Family Lines and Chessie System Railroad. In 1983 CSX combined the Family Lines System units as the Seaboard System Railroad and later became CSX Transportation when the former Chessie units merged with the Seaboard in December 1986. Effective January 1, 1983, the Seaboard Coast Line Railroad became Seaboard System Railroad after a merger with the Louisville and Nashville Railroad and Clinchfield Railroad. For some years prior to this, the SCL and L&N had been under the common ownership of a holding company, Seaboard Coast Line Industries (SCLI), the company's railroad subsidiaries being collectively known as the Family Lines System which consisted of the L&N, SCL, Clinchfield and West Point Routes. During this time, the railroads adopted the same paint schemes but continued to operate as separate railroads.

Brand/Importer Information: 
In 1924 Stephan Schaffan, Sr. founded the Atlas Tool Company in Newark, New Jersey. In 1933 his son, Stephan Schaffan, Jr., came to work for his father at the age of sixteen. Steve Jr. built model airplanes as a hobby and frequented a local hobby shop. Being an enterprising young man, he would often ask the owner if there was anything he could do to earn some extra spending money. Tired of listening to his requests, the hobby-store owner threw some model railroad track parts his way and said, "Here, see if you can improve on this".
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.
