Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
LNER Class A3 4472 Flying Scotsman was the first steam locomotive to officially reach 100 mph (160 km/h), on 30 November 1934. 41 018 climbing the Schiefe Ebene with 01 1066 as pusher locomotive (video 34.4 MB) A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam.
The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. [12] They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747. [12]
Steam on industrial lines remained until the 1980s. With regular maintenance, British steam locomotives typically lasted for approximately 30 years of intensive use, before major components would need to be replaced or overhauled. For a steam locomotive built in 1960, the economic lifespan would have led to it being withdrawn in the 1990s.
A Big Boy locomotive.This example is Union Pacific 4014. 4-8-8-4 wheel arrangement. A 4-8-8-4 in the Whyte notation for the classification of steam locomotives by wheel arrangement, is a locomotive with a four-wheel leading truck, two sets of eight driving wheels, and a four-wheel trailing truck.
As well, steam locomotive exhaust systems typically vent cylinder steam exhaust through the chimney, to enhance the draught through the boiler. Chimneys are designed to carry the exhaust steam and smoke clear of the driver's line of sight while remaining short enough to clear overhead structures. Some chimneys included apparatus to suppress the ...
They also hoped that the new S1 steam locomotive would have a performance equal to their Pennsylvania Railroad class GG1 electric engine and would be capable of hauling a 1,000-ton passenger train at 100 mph. [4] A conference was held between Baldwin Locomotive Works officials and W. F. Kiesel, J. V. B. Duer and W. R. Elsey for PRR, where PRR ...
The first steam-powered locomotive on rails was built by Richard Trevithick in either 1802 or 1804. He built several locomotives, and although the success of his 1802 locomotive at Coalbrookdale is questioned, his 1804 locomotive ran near the Pen-y-Darren Ironworks in Merthyr Tydfil, South Wales successfully enough to haul five wagons of iron for nine miles, winning a wager.
