The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail.It was designed specifically to operate services through the Channel Tunnel between Great Britain and France.
OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard gauge model railway standard in the United Kingdom, [1] outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 ft (304.8 mm), or 1:76.2), and the only one to be marketed by major manufacturers.
His responsibilities within Tri-ang were the development of the OO/HO range and he was "a prime mover in starting and promoting" the TT gauge. [4] Tri-ang also manufactured a garden railway system called Tri-ang Minic Narrowgauge Railway, thus being known as TMNR. This was a 10.25" gauge passenger carrying system using 2 rail electric pick-up ...
The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while H0e is used for European prototypes. In Britain, the term OO9 is used. [1] All these terms refer to models of narrow-gauge railways built to the world's most popular model railway scale of HO (1:87) but using a track gauge of 9 mm (0.354 in)—the gauge used for N scale models of standard-gauge ...
Improved ventilation was needed for the tunnel though, and a forced ventilation fan house was built around the East portal, powered by the same traction current. This involved providing a closed door to the tunnel portal to control airflow, which opened automatically as a train approached. All Z-1s were retired and scrapped in August 1956. [1]
For the construction of the Lötschberg line and the main tunnel two special railways had to be constructed to bring material from Frutigen or the junction at Naters near Brig to the portals of the Lötschberg tunnel. The gauge of the railways was 750 mm (2 ft 5 + 1 ⁄ 2 in), the maximum gradient was 60 per thousand (6%) and the minimum curve ...

Trains on the Shinkansen network operate on 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge track and have a loading gauge of 3,400 mm (11 ft 2 in) maximum width and 4,500 mm (14 ft 9 in) maximum height. [46] This allows the operation of double-deck high-speed trains.
