An early development was the application of a steam brake to locomotives, where boiler pressure could be applied to brake blocks on the locomotive wheels. As train speeds increased, it became essential to provide some more powerful braking system capable of instant application and release by the train operator, described as a continuous brake ...
Steam is supplied to the steam brake cylinders from the locomotive boiler via a valve (the brake valve) which may have several fixed settings or be infinitely variable. The piston in the steam cylinder is set in motion by the steam admitted, the piston rod transfers the brake force via a system of rods to the brake blocks of the vehicle, thus achieving the braking effect.
Brake pads should be checked at least every 5,000 miles for excessive or uneven wear. Although brake pad wear is unique to each vehicle, it is generally recommended that brake pads be replaced every 50,000 miles, [6] while brake discs (or rotors) typically last longer, needing replacement every 70,000 miles.
Brake shoe / Brake block Cast iron or composite material that rubs on all the driving wheel treads for braking. [1] [2] [3]: 13 Sand pipe Deposits sand directly in front of the driving wheels to aid traction on steep gradients, when starting or when the rail surface is not dry and clean. [5] [3]: 69 Coupling rods / Side rods
Counter-pressure brakes were found especially on steam engines that worked long inclines and on rack railway locomotives (e.g. on the Vienna Kahlenberg Railway (Kahlenbergbahn), relieving brake blocks and tyres from high levels of wear and tear that they would otherwise be subjected to.
