As soon as the second-largest steam locomotive builder within the united states, American Locomotive corporation (Alco) produced 75,000 locomotives, between them such well-known examples because the 4-6-4 Hudsons and 4-8-4 Niagaras outfitted for the recent York primary, and the 4-6-6-4 Challengers and 4-8-8-4 sizeable Boys equipped for the Union Pacific. Alco Locomotives is the 1st ebook to inform the total tale of this corporation vital to American railroad history—and liked via railfans for its wealthy background and its underdog allure. famous rail historian Brian Solomon appears to be like again on the founding of Schenectady Locomotive Works in 1848 and proceeds to hide that company’s merger with a number of smaller locomotive developers in 1901 to shape Alco. Solomon describes the locomotives that made Alco’s identify all over the world, from the normal designs like Mikados, Atlantics, and Mallets to the extra robust and flashy post–World battle I types. His exact, richly illustrated narrative re-creates the drama of a tricky, formidable corporation within the American tradition—rising many times to the calls for of an ever-changing and economic system. Solomon additionally covers Alco electrics (built in partnership with GE), in addition to the company’s profitable and quirky diesel choices, together with the RS-2 and RS-3 street switchers, FA/FB highway freight devices, PA highway passenger diesel, and the wares of Canadian associate Montreal Locomotive Works. Enlivened by way of a number of historic pictures, smooth photographs, curious info, and firsthand money owed, this background is a whole, attention-grabbing, and becoming tribute to a real icon of yank railroading.

Another weakness, repeated in subsequent designs, was the control system. Here, the technology was lacking for a really foolproof and simple method of controlling the relationships between diesel, generator and traction motors. The Ward-Leonardo system was used, which meant that the driver controlled the speed of the locomotive through a control handle which changed the resistance through which passed the excitation current. The five traction motors, one for each driving axle, were arranged in parallel; because of lack of experience in this kind of installation, and for the sake of simplicity, they were self- From Recuperation to Reconstruction, 1922 - 1929 41 cooling, which meant that at slow speeds they were liable to overheat because the cooling air passed over them at a corresponding speed.
M. Oshkurov the diesel engine specialist, Academician V. F. Mitkevich (who was interested in electrical systems), and D. B. SamoilenkoGol'dman, who early in 1921 seems to have aroused Gakkel"s interest by proposing that he design a locomotive using an aero-engine with electric transmission. It was this group of experts, then forming the VSNKh Committee for the Study and Design of Diesel Locomotives, which examined and approved Gakkel"s 1000 hp project and sent it on to Gosplan in February 1922, together with a cost estimate.
Key: I, diesel engine; 2, generators; 3, traction motors; 4, exciters; 5, fans; 6, fuel; 7, lubricants; 8, battery; 9, radiator; 10, water tank; I I, driver's control handle; 12, semi-rigid coupling; 13, hand-brake. Vickers engine was used, and the generators were of 'Volta' submarine type. The traction motors were made at the Elektrik Works (formerly Deka), and the Putilov Works was entrusted with the chassis. The latter was designed by Raevskii, and was quite novel. Because of the weight and length of the locomotive it was decided to mount it on sprung trucks; apart from the usual axleweight problem it was also feared that the vibrations of the diesel engine would have a damaging effect on the track.
