Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing the cam lever, thus more quickly than wheels with solid axles and nuts. On the negative side, a quick-release hub renders a wheel more vulnerable to theft and care must be taken to ensure that the mechanism ...

The use of a return connecting rod to a shaft beneath the boiler with overhung cranks also avoided the need for an internal crank. For Stephenson's designs, this crank axle would also have carried the locomotive's weight, not being merely a crankshaft, and so this avoided a particularly difficult piece of forging work.
The experimental AA20 4-14-4 was the only locomotive ever to have seven coupled driving axles. It used lateral motion devices on the first and seventh axles as well as blind drivers on the third, fourth and fifth axles but these measures were not enough to allow it to negotiate curves without damaging the track, derailing, or both.
The Baldwin DR-12-8-1500/2 (known informally as the Centipede) was the Baldwin Locomotive Works' first serious attempt at a production road diesel locomotive.The Baldwin type designation was ' DR-12-8-1500/2, ' meaning Diesel Road locomotive, with 12 axles (8 of which were driven), and two engines of 1,500 horsepower (1,100 kW) each.
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.
The 82.5 cm (32 inches) long piece has fitted to one end a 15 cm (6 inches) long bronze handle, the other handle being lost. [ 32 ] [ 31 ] An true iron crank about 40 cm (16 inches) long was excavated, along with a pair of shattered mill-stones of 50 to 65 cm (20 to 26 inches) diameter and diverse iron items, in Aschheim , close to Munich .
