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.
An axle counter is a system used in railway signalling to detect the clear or occupied status of a specified section of track. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section.

Safetran was founded in 1920 [4] when Safetran's predecessors started developing and fielding products for the growing railroad infrastructure (See Timeline of United States railway history for details about the significant development of the United States' rail infrastructure.)
More than 10 years ago, the California High-Speed Rail Authority launched its effort to buy the property needed for the state’s planned bullet-train route through the central San Joaquin Valley ...
A rail vehicle wheelset, comprising two wheels mounted rigidly on an axle A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle allowing both wheels to rotate together. Wheelsets are often mounted in a bogie (" truck " in North America ) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle.
The 171-mile stretch of rail running between Merced and Bakersfield could be operational as early as 2030, with testing of the bullet trains slated to begin in 2028, according to the High-Speed ...
The signals which are present in the rail are detected by antennas mounted underneath the front airdam of TGV trains, approximately 1 metre (3 ft) forward of the front axle. These antennas work by inductively coupling to the AC signal shunted between the rails by the first axle. There are four redundant antennas per train, two at each end.
