Model Information: Atlas introduced the Kato-produced RS-3 in 1983. They followed up with the RSD-4/5 in 1987, also Kato-produced and sold by both Atlas and Kato under their own brand name. The models were redesigned in 1999 and production moved to China. The models were again modified in 2001 (RS-3) and 2004 (RS-4/5) and from then on featured Atlas "Slow-Speed" motors. The RS-3 and RSD-4/5 share the same internal mechanism.

The early releases were the first locomotive produced by Kato for Atlas. It was vastly superior to the earlier models produced by Roco for Atlas. The combination of the split-frame design, directional lighting and 5-pole motor with bearing blocks to hold the worm gear in place made it the first "modern" N-Scale design for a North American locomotive.
DCC Information: Unfortunately the one modern feature it lacks is a single-lightboard design to permit a "drop-in" decoder board installation. The split-board requires some soldering and careful installation to upgrade even the most modern edition of this locomotive to DCC. Special split decoders are available to convert these models to DCC. Some soldering required. TCS makes the 1278-CN which works pretty well.
Prototype History:
The ALCO RSD-4 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1.2 MW), that rode on three-axle trucks, having an C-C wheel arrangement.

Used in much the same manner as its four-axle counterpart, the ALCO RS-3, though the six-motor design allowed better tractive effort at lower speeds. Due to the inadequate capacity of the main generator, this model was later superseded in production by the ALCO RSD-5

From Wikipedia
Road Name History:
The Utah Railway was completed in 1914 to connect several coal mines south and west of Helper, Utah (on the Rio Grande mainline) with the outside world. The Utah branches connect with the Rio Grande at Utah Railway Junction, just northwest of Helper. The Utah then utilizes trackage rights on the Rio Grande northwest to Thistle. The remainder of the line between Thistle and Provo is on paired track with Rio Grande (later SP then UP.) Total mileage is 95.

In the steam era, the locomotive fleet consisted of a quartet of 2-8-0’s (likely for switching the mines), nine 2-10-2’s for road service, and a trio of 2-8-8-0’s which were probably used as helpers. All seem to have been of Union Pacific design.

The Utah Railway dieselized in 1952 with seven Alco RSD4’s and a bit later an RSD5. As traffic began to build in the modern era, they picked up three RSD15’s and an RSD12. In 1985, they began relying on leased power from Helm and later from MK.

The 1996 merger of Southern Pacific and Union Pacific changed things for the Utah. First, they were contracted by BNSF to handle their haulage trains over a portion of the “Central Corridor” as UP calls the old Rio Grande. Secondly, UP granted Utah trackage rights east from Utah Railway Junction all the way to Grande Junction, Colorado which linked the Utah Railway to several more large coal mines. At this point, Utah hired a number of new people and leased more than a dozen additional diesels for heavy road service. Now stretching from Grande Junction to Provo, Salt Lake City and Ogden, the Utah Railway operates 423 miles of track. In addition to coal, UTAH moves aggregate, brick, building materials, cement, chemicals and petroleum products.

In 1999, Utah purchased the Salt Lake City Southern, a 25 mile shortline in the area from its owner RailTex. Owned by a string of mining companies over the years, the Utah was sold in 2002 to the Genesee & Wyoming shortline group for $54 million. Today's collection of photos takes us from 1975 to 1988.
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.
