Atlas - 2152 - Locomotive, Diesel, Alco RSC-2 - Monon - 23

Model Information: This model was introduced by Atlas in July of 1968. It was produced for them by Mehanotehnika (Mehano) in Yugoslavia. 5 road names were offered, but only the UP actually operated the prototype. When Atlas discontinued production of this model, no other brand stepped in to make them. The mechanism is a 5-pole open-frame motor which drives the two rear axles of the rear truck.

Prototype Info: This engine is a variation of the Alco RS-2 specifically for railroads that operated on lighter track. The axle spacing on this engine is symmetrical within the truck, unlike other road switchers where the middle axle is typically closer to the end axle than to the interior axle.

Prototype History: The ALCO RSC-2 was a diesel-electric locomotive of the road switcher type that rode on three-axle trucks, having an A1A-A1A wheel arrangement. Used in much the same manner as its four-axle counterpart, the ALCO RS-2, though the wheel arrangement lowered the axle load for operation on light rail such as are found on branch lines.

The Milwaukee Road was the first railroad to take delivery of the RSC-2, initially assigning them to their Valley Division (headquartered near Wausau, Wisconsin) in November 1946. This was done in order to study the effects of an all-diesel roster (i.e. no steam locomotives available as protection power). The experiment was deemed a success and soon all steam locomotives were gone from the Valley Division. RSC-2s would faithfully serve the Milwaukee Road for many years, until being replaced in turn by the EMD SDL39.

ALCO also exported these units to the state railway of Portugal, where Portuguese Railways (CP) designated them Série 1500. These locomotives were built for the Iberian track gauge of (1,668 mm (5 ft 5 21⁄32 in)). The last units in Portugal served in regular passenger service into the first decade of the 21st century. Of these, five are still running today, 60 years after their arrival (one is a museum locomotive, while the other four are owned by track maintenance companies). Five units were exported to the Algerian National Railways where they were used in passenger train service.

Road Name History: The Monon Railroad (reporting mark MON), also known as the Chicago, Indianapolis, and Louisville Railway (reporting mark CIL) from 1897 to 1956, was an American railroad that operated almost entirely within the state of Indiana. The Monon was merged into the Louisville and Nashville Railroad in 1971, and much of the former Monon right of way is owned today by CSX Transportation. In 1970 it operated 540 miles (870 km) of road on 792 miles (1,275 km) of track; that year it reported 1320 million ton-miles of revenue freight and zero passenger-miles. (It showed zero miles of double track, the longest such Class I railroad in the country.)

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.

Manufacturer Information: Mehano is a Slovenian toy manufacturer located in Izola, Slovenija. The company was founded as Mehanotehnika and was producing toys starting in June 1953. They first exhibited at the Nuerenberg Toy Fair in 1959. Mehano produced a number of different locomotives and rolling stock models for the North American market in the 1960s and 1970s. Companies such as Atlas and Life-Like imported a huge variety of their products. Generally they can easily be recognized as they are stamped "Yugosolavia" on the underframe. The company was formally renamed "Mehano" in 1990. Izola today is part of the country of Slovenia since the breakup of Yugoslavia.
Mehano filed for bankruptcy in 2008, but still continued to exist and operate. Since 2012, Mehano products are distributed by Lemke.
