The Pennsylvania Railroad's class DD2 was a single prototype electric locomotive never placed into series production. [3] It was intended as an improved and simplified GG1 for use on the planned, but never built, extension of the PRR's electrification west of …

根据设计，PRR阿尔图纳工厂于1938年2月7日制造了DD2-5800号机车。 DD2-5800号机车长22100 mm，自重200 t。 机车车架分为前后两段，由杵臼关节相联结，使其能通过较小半径弯道。 机车装备有8台WE制428-A型牵引电动机，单台功率625 hp（459.69 kW）。 动轮直径为1575 mm，共4轴。 车体前后各有2对无动力导从轮。 DD2-5800号机车的尺寸图. 运用. 虽然DD2-5800号机车的动轮数量比GG1型机车少，130 t的黏着重量比GG1型机车的137 t黏着重量少， …

The PRR wanted a dual passenger-freight electric locomotive and developed a 2-B+B-2 that incorporated the best features of the previous electric locomotives. The Altoona Shops built a single prototype of this husky streamlined 4-4-4-4 Class DD-2 and outshopped it in 1938.

2021年1月14日 · PRR class AA1 10002 was one of two experimental D.C. third-rail units the railroad built when planning the electrification for New York’s Pennsylvania Station, which opened in 1910. PRR’s lone “odd class D” had a wheel arrangement based on the 4-4-0 steam locomotive; it tested on a short section of catenary-equipped Long Island Rail Road track.

The Pennsylvania Railroad 's steam locomotive class D2 (formerly Class B, pre-1895) comprised twenty 4-4-0 locomotives intended for mountain passenger helper service, constructed at the railroad's own Altoona Works (now owned by Norfolk Southern) during 1869–1880. [4] .

The Pennsylvania Railroad's class DD2 electric locomotive was a single prototype locomotive never placed into series production. It was intended as an improved and simplified GG1 for use on the planned, but never built, extension of the PRR's electrification west of …

The DD2 was conceived as a dual-purpose locomotive with 5,000 horsepower. PRR built the lone DD2 in February of 1938, and although it was never duplicated, it worked until it was scrapped in the early 1960's.

2018年7月18日 · The PRR motive power engineers decided to develop a 2-D-2 (4-8-4 wheel arrangement) electric locomotive. They started with the P5a and added an additional driving axle which was powered by two 625 HP motors giving the new locomotive a total of 5,000 HP as compared to the 3,750 HP of the P5a.
