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 modules are marked by their standard three running tracks (two are "mainline" tracks and the third is the "branchline" track) that are required on all modules. These three tracks are set on 1.5-inch (38 mm) centers near the viewing side of the modules.
sTTandard, [18] Polish TT-scale (1:120) modules organization. T-TRAK, [19] is a modular system that uses table-top modules, 2 + 3 ⁄ 4 inches (70 mm) high, which set on tables, that are not part of the modules, but are often found at sites which members meet. It uses a specific track interface, which has joiners which hold the modules together ...

Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems.
HŽ series 7022 is a class of low-floor diesel multiple unit built for Croatian Railways (Croatian: Hrvatske željeznice, HŽ) by Croatia based company TŽV Gredelj.The prototype of diesel electric multiple unit for regional traffic is a 3-part train set composed of two end motor modules containing driver's cab and one middle motor module without driver's cab.
Grooved rail, used when track is laid in places traversed by other vehicles or pedestrians. A grooved rail, groove rail, or girder rail is a special rail with a groove designed for tramway or railway track in pavement or grassed surfaces (grassed track or track in a lawn). The head on the right-hand side of the rail bears the vehicle's weight.
TRAK is defined in a logical way - that is to say free of any notion of how TRAK is implemented in any tool or any architecture description language. TRAK has 24 architecture viewpoints which are grouped into 5 perspectives. Each viewpoint belongs to a single perspective and specifies a single view (type). Each viewpoint specifies what sets of ...
