An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
The first electric elevated railway was the Liverpool Overhead Railway, which operated through Liverpool docks from 1893 until 1956. In London, the Docklands Light Railway is a modern elevated railway that opened in 1987 [8] and has since expanded. [9] The trains are driverless and automatic. [10]
Traditionally these are the wheels, axles, axle boxes, springs and vehicle frame of a railway locomotive or wagon. [1] The running gear of a modern railway vehicle comprises, in most instances, a bogie frame with two wheelsets. However there are also wagons with single axles (fixed or movable) and even individual wheels.
Detail of suspender, wheel, and motor of a GTW 72 train. The cars are suspended from a single rail built underneath a supporting steel frame. The cars hang on wheels which are driven by multiple electric motors operating at 600 or 750 V DC, fed from a live rail below the running rail. [22] A vehicle leaving the Wagenhalle Oberbarmen depot

The system consisted of an elevated track with the cars suspended below the track, like the Wuppertal Schwebebahn or H-Bahn systems in Germany. A 1.6-kilometre (0.99 mi) test track in Margao, Goa started trials in 2004, but on 25 September, one employee was killed and three injured in an accident. [ 16 ]
The Dresden Suspension Railway (Dresden Schwebebahn), which hangs from an elevated rail, is the only suspended funicular in the world. [27] The Fribourg funicular is the only funicular in the world powered by wastewater. [14] Standseilbahn Linth-Limmern, capable of moving 215 t, is said to have the highest capacity. [28]
The rotating shaft of the motor was also the axle for the wheels. In the case of French TGV power cars, a motor mounted to the power car's frame drives each axle; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks bogies to pivot. By mounting the relatively heavy traction motor directly to the power car ...
