AAR wheel arrangement

Locomotive wheel arrangement is how the wheels of the locomotive are arranged by type, position, and connections. There are several notations used to describe wheel arrangements. In the United States and the British Isles, the Whyte notation is generally used for steam locomotives. In Europe, the UIC classification scheme is generally used, especially for diesel and electric locomotives. British practice uses a slightly simplified form of that notation for diesels and electrics. The United States uses the ...

The GG1s were large locomotives, 79 ft 6 in (24.23 m) long and weighing 477,000 lb (216,000 kg). The main body was a single unit formed as a bridge-truss framework and clad in welded steel plate. The driving cabs were set up high about a third of the way along the locomotive from each end for greater crew safety in an accident. A narrower section of nose in front of the cab windows enabled view forward, although the nose remained full height to carry the current-collection pantograp ...

The electrical distribution system the GG1s relied on was replaced with a newer system with voltage suited for other locomotives, rendering the Baldwin electrics unusable. These locomotives have now all been retired with many units scrapped and only a few surviving to sit, unused. They have been supplanted primarily by the AEM7 "toaster" locomotives. It has often been proposed for a GG1 to be restored to operating condition. At least one unit is in sufficiently good shape for this to be feasible, but a compatible catenary system does not exist in the US, so the effort would be useless. Furthermore, the electrical ...
