Unspecified 0-4-2 Locomotives in the USA

Class Baldwin (Locobase 8429)

Data from 1891 edition of Matthais Forney's Catechism of the Locomotive, pp. 164-165. See also Baldwin Locomotive Works: Illustrated Catalogue of Locomotives ( ), 7-8; and "Steam Cars on City Passenger Railways", Railway World, Quarto Volume 3, No. 12 (24 March 1877), p. 268.

Locobase believes this is the tramway locomotive described on pp 344-345 of David Kinnear Clark's Tramways Their Construction and Working (London: Crosby, Lockwood & Co, 1878). It was tested by the Market Street Passenger Railway Company against six steam cars produced by Gilbert Bush & Company of Troy, NY (Locobase 12251). The boiler pressure is an estimate.

Railway World's report fully describes the Baldwin: "The body is about five feet longer than an ordinary street car. the extra space being occupied by the firebox and boiler, which are in the front end of the car. All the machinery and running gear are entirely separate from the car body, being supported upon a wrought-iron frame. the car body merely resting upon the frame back of the boiler. The machinery hangs under the car. the cylinders being under the rear end and outside of the wheels. with which they are connected by crank-pins exactly similar to the driving wheels of a locomotive. All the wheels are coupled together by connecting bars. securing uniformity of motion. The wheels are placed six feet apart, the same distance as an ordinary horse car. The cylinders, which are 8 inches diameter and to inches stroke. are boxed in to protect them from mud and dust. The boiler is of steel. double riveted, capable of standing a steam pressure of 300 pounds to the square inch. while the pressure used in the trial on the ztst inst. was from 100 to 113 pounds. It is controlled by a powerful brake, the lever of which is directly under control of the engineer. and beside, the steam may be used for a quick stop by means of the reverse lever.

Gene Connelly's Baldwin list shows that no fewer than 91 0-4-2Ts with 10 x 14" cylinders and 35" drivers were delivered between 1878 and 1892. See Locobases 11577, 11603, 11610, and 11883 for street railways that operated this basic design.
