Model Information: Kato introduced this '2nd generation" SD40 model in 1991. Later, in 1995, they started producing SD45s with the same mechanism. In 2002 they revised an re-released the SD40. In 2010 revised and re-released the SD45.
When it first came out, the Kato 1991 SD40 was considered very innovative for its time. The model features full pilots with body-mounted couplers. These models (both pre and post revision) run very well with excellent all-wheel pickup and drive. They are quiet and smooth running (though quite fast compared to new Atlas slow-speed mechanisms). They can really pull and handle fairly well on sharp curves. The key difference between the early and later version of the mechanism is the DCC support.

DCC Information: The early versions (pre-2002) are considered DCC-friendly. The later revisions support drop-in decoders. I suspect that it is easier and cheaper to take one of the old shells and drop it over a new chassis than to try to convert an old mechanism to DCC.
Prototype History: 
The EMD SD40 is a 6-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972. In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. These included six-axle models SD38, SD40, SDP40 and SD45. All shared standardized components, including the frame, cab, generator, trucks, traction motors, and air brakes. The primary difference was the power output, with SD40 being rated at 3,000 hp (2,240 kW) from a turbocharged V16.
856 examples of this locomotive model were built for American railroads, 330 were built for Canadian railroads, 72 were built for Mexican railroads, 6 were built for the Guinea-Boke Project, and 4 SD40Ms riding on 5 ft 3 in (1,600 mm) gauge trucks were exported to Brazil.

Road Name History: 
The Pennsylvania Railroad (reporting mark PRR) was an American Class I railroad, founded in 1846. Commonly referred to as the "Pennsy," the PRR was headquartered in Philadelphia, Pennsylvania.
The PRR was the largest railroad by traffic and revenue in the U.S. for the first half of the twentieth century. Over the years, it acquired, merged with or owned part of at least 800 other rail lines and companies. At the end of 1925, it operated 10,515 miles of rail line; in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific or Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Central (NYC), which carried around three-quarters of PRR's ton-miles.
At one time, the PRR was the largest publicly traded corporation in the world, with a budget larger than that of the U.S. government and a workforce of about 250,000 people. The corporation still holds the record for the longest continuous dividend history: it paid out annual dividends to shareholders for more than 100 years in a row.
In 1968, PRR merged with rival NYC to form the Penn Central Transportation Company, which filed for bankruptcy within two years. The viable parts were transferred in 1976 to Conrail, which was itself broken up in 1999, with 58 percent of the system going to the Norfolk Southern Railway (NS), including nearly all of the former PRR. Amtrak received the electrified segment east of Harrisburg.

Since that time, KATO has come to be known as one of the leading manufacturers of precision railroad products for the modeling community. KATO's parent company, Sekisui Kinzoku Co., Ltd., is headquartered in Tokyo, Japan.
In addition to producing ready-to-run HO and N scale models that are universally hailed for their high level of detail, craftsmanship and operation, KATO also manufactures UNITRACK. UNITRACK is the finest rail & roadbed modular track system available to modelers today. With the track and roadbed integrated into a single piece, UNITRACK features a nickel-silver rail and a realistic-looking roadbed. Patented UNIJOINERS allow sections to be snapped together quickly and securely, time after time if necessary.
The Kato U.S.A. office and warehouse facility is located in Schaumburg, Illinois, approximately 30 miles northwest of Chicago.
