The Detroit could start from cold in as little as 90 seconds. A two-cylinder double-acting uniflow engine was mounted under the floor driving the back axle; double slide valves were driven by a Joy valve gear. The car had only four controls: a steering wheel, a brake pedal, a trip pedal for variable cut-off and reversing, and a foot-operated ...
Tatra used this layout until end of production of T700 in 1999. In case of T613 and T700 Tatra used layout with engine above rear axle, which reduced some disadvantages of RR layout. Mercedes-Benz also produced several models of RR cars in this period, starting with the 130H (1934).
Of the 127 cars in service, 85 were converted between 1972 and 1978 into two-car trains or double-ended three-car trains. The entire fleet was withdrawn by 1984 in favor of modern rolling stock. [53] San Francisco Municipal Railway: United States: 40: 80: 120: Five double-ended non-patent cars purchased in 1939. Ten cars in 1948 and another 25 ...
The first step in planning a substation layout is the preparation of a one-line diagram, which shows in simplified form the switching and protection arrangement required, as well as the incoming supply lines and outgoing feeders or transmission lines. It is a usual practice by many electrical utilities to prepare one-line diagrams with ...
These substations may consist of two to eight or more primary transformers connected to the same secondary bus to provide reliable facility power. Examples of such single facilities include airports, hospitals , major data processing centers (especially those using uninterruptible power supplies ), and sports arenas that regularly broadcast ...
The C car is normally at the opposite end of a consist from the locomotive. [ 1 ] [ 2 ] Unlike the LIRR's electric multiple unit rail cars, which use fully automatic couplers making all connections between the rail vehicles (mechanical, air brake, and electrical) without human intervention, the C3 uses more traditional connectors.
This is a list of the power supply systems that are, or have been, used for railway electrification. Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors.
Trams have been used since the 19th century, and since then, there have been various uses and designs for trams around the world. This article covers the many design types, most notably the articulated, double-decker, drop-centre, low-floor, single ended, double-ended, rubber -tired, and tram-train; and the various uses of trams, both historical and current, most notably cargo trams, a dog car ...
