T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards.
NTRAK (all upper case letters) is one of several model railroad module standards. It is the most popular standard for use in United States N scale . NTRAK allows modelers to participate in a large layout but only invest a small amount of space at their own home.

For 00 therefore the track is about 12.5% narrower than it should be for the scale used. EM and P4 standards correct this anomaly by adopting a wider track gauge. The globally more-widespread international NEM and NMRA scale standards are relatively rare in Great Britain and used almost exclusively by those modelling foreign prototypes.
This scale is today the most popular modelling scale in the UK, although it once had some following in the US (on 19 mm / 0.748 in gauge track) before World War II. 00 or "Double-Oh", together with EM gauge and P4 standards are all to 4 mm scale as the scale is the same, but the track standards are incompatible. 00 uses the same track as HO (16 ...
A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
In Track Warrant Control, or TWC, the train dispatcher issues "track warrants" via radio that authorize the train between two specified limits. The limits are often mileposts or stations. The track warrant may authorize a train to proceed to a station and "clear the main" or enter a siding so an oncoming train can pass.
The telematics data is used (via Fleet Telematics Systems) by Fleet Management Systems to let fleet operators keep track of vehicle and driver performance, such as fuel consumption, safety events, and repair time. [1] Because of the demanding standards, engine development is expensive, and truck-based engines are reused in many fields.
