Prototype: Same as model 37610, but with a different road number.
Model: Booster unit for real doubleheading with model 37610. Highefficiency motor, controlled from the decoder in the 37610 locomotive. 2 axles powered. 4 traction tires. Lights as well as acceleration and braking delay controlled from the decoder in the 37610 locomotive. Special coupling with multiconductor electrical connection between the two locomotives. Close coupler in standard coupler pocket at both ends, can be replaced by American couplers or by a cover plate. Length over couplers 23.5 cm / 9-1/4".
- Metal construction. Real multiple unit operation: 2 locomotives controlled from a single decoder. Pilot with guide mechanism at the end coupled to a train swings out a little on curves. Diesel motor sound effects vary according to how the locomotive is running (only with 37610). Road numbers 600 (37610) and 601 (49610).
Some things are remembered long after their natural lives have passed - they are history. This applies particularly to the American Locomotive Company"s (ALCo) "PA" locomotive. Standing for "passenger A-unit" with an engineer's cab, the PA was introduced in 1946, and became an immediate success with the new deluxe trains. Although a competing locomotive manufacturer sold more passenger units overall, this sleek, powerful design and the PA"s modern, powerful technology quickly found the hearts of railroad employees and passengers. The PA was used on almost all of the main lines in the United States, but their greatest presence was in the Southwest. Particularly well known were the bright yellow Union Pacific PA"s and the classic silver and red of the Santa Fe, but also the "Daylight" version of the Southern Pacific in orange and red. In the Southeast, Southern Railway"s PA"s worked a train by the name of the "Pelican". In the northeastern United States, the elegant gray tones of the New York Central"s PA"s matched the passenger cars of the same color which they pulled, thus forming a complete picture.
In conjunction with the "name trains", the striking, harmonious shape of the PA formed an ideal combination of powerful technology and aesthetic design. Railroad crews favored the PA because of its smooth ride and the safety provided by the long nose and sturdy superstructure. The rhythmic, full sound of the 4-stroke diesel motors, which these diesels made while accelerating, was incomparable among railroad experts. The fans named the PA an "Honorary Steam Locomotive" because of a peculiarity of the ALCo 244 diesel prime mover when starting up. Until the fuel started burning completely, thick clouds of black smoke would pour from the exhaust stacks, and then the PA would roar off. While the ElectroMotive Diesel E unit had been a continuation of passenger locomotive development dating back to the 1930"s, the PA was a development born of post-war optimism toward the future of railroad passenger service.
The 49610 locomotive can be operated only in conjunction with a 37610 locomotive. Can be used on track with a minimum radius of 360 mm / 14-3/16".
