A 6×4 or six-by-four is a vehicle with three axles, with a drivetrain delivering power to two wheel ends on two of them. It is a form of four-wheel drive but not one of all-wheel drive. Classic Truck twin rear axles providing drive via 8 wheels: 6x6 6X6, a standard class of medium-duty trucks Classic Mil spec: 6x6 drive train power to rear and ...
General Motors, BMW, and DaimlerChrysler collaborated on a system named "Two-Mode Hybrid" as part of the Global Hybrid Cooperation. The technology was released in the fall of 2007 on the Chevrolet Tahoe Hybrid. The system was also featured on the GMC Graphite SUV concept vehicle at the 2005 North American International Auto Show in Detroit. [32]
Particularly in North America for several decades, the designation AWD has been used and marketed – distinctly from 4×4 and 4WD – to apply to vehicles with drive train systems that have permanent drive, a differential between the front and rear drive shafts, and active management of torque transfer, especially following the advent of the anti-lock braking system (ABS).

Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
The maximum distance is determined on the restriction of a maximum allowed reply delay of 42.7 μs (where for longer distances a second mode is used that allows up to 83.4 μs with reduced throughput, in case MVB is used for switchgear on the track side) while most system parts communicate with a response time of a typical 10 μs.
Hydraulic hybrid vehicle systems consists of four main components: the working fluid, reservoir, pump/motor (in parallel hybrid system) or in-wheel motors and pumps (in series hybrid system), and accumulator. In some systems, a hydraulic transformer is also installed for converting output flow at any pressure with a very low power loss. [3]
