This was the standard light switcher locomotive of the USRA types, and was of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification. A total of 255 locomotives were built under USRA control; these were sent to the following railroads:
An electric switcher in Salzburg, Austria The majority of modern switchers are diesels, but countries with near-total electrification , like Switzerland, use electric switchers. Prior to the introduction of diesel-electric locomotives, electric shunting locomotives were used to an extent in Great Britain where heavy trains needed to be started ...
The EMD SW7 was a diesel switcher locomotive built by General Motors Electro-Motive Division between October 1949 and January 1951. [2] It was powered by a 1,200 horsepower (895 kW)12-567A engine. [1] The SW7 replaced the earlier 1,000 horsepower NW2 switcher in EMD's catalog. [3] A total of 489 SW7 locomotives were produced.
Trains in one direction were pulled through the tunnel, by a series of electric locomotives that lasted until the end of steam; in the other direction, the train simply drifted down the slope. Dieselization made the electrification unnecessary and it was discontinued in 1952.
Whaleback tender built for the Kahului Railroad in 1928. A form peculiar to oil-burning engines was the "whaleback" tender (also sometimes called a "turtle-back" or "loaf" tender). This was a roughly half-cylindrical form with the rounded side up; the forward portion of the tank held the oil, while the remainder held the water.
The ALCO S-2 and S-4 are 1,000-horsepower (746 kW) diesel electric switcher locomotives produced by ALCO and Canadian licensee Montreal Locomotive Works (MLW). [1] Powered by turbocharged, 6-cylinder ALCO 539 diesel engines, the two locomotives differed mainly in their trucks: the S-2 had ALCO "Blunt" trucks; the S-4, AAR type A switcher trucks ...
The SW1200 was the third model of 1,200 hp SW series switchers built by EMD. It was a successor to the SW7 and SW9.Compared to its direct predecessor, the SW9, the SW1200 differed in that it used the improved and more reliable 567C engine, compared to the SW9's 567B engine.
The program was initiated in response to a system-wide need for more than 200 additional four-axle diesel road switchers to meet projected motive power demands on branch lines and secondary main lines. Santa Fe's aging fleet of F7 units were approaching retirement age in 1970. These units were remanufactured into switchers and named CF7.
