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.
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
KV-85 (Object 239) – A KV-1S with the 85 mm D-5T cannon in a new turret, with the ball mounted hull machine gun repositioned to the right of driver (now fixed mount) and the hole welded shut; 148 of these tanks were produced in the second half of 1943 until the spring of 1944 as a stopgap until the IS tank series entered production.
The Class 395 can operate at a maximum speed of 140 mph (225 km/h) under 25 kV AC overhead electrification on High Speed 1, and 100 mph (160 km/h) on 750 V DC third-rail supply on conventional lines. It is typically formed as a six-car train, although they can be rapidly coupled to one another to form a 12-car train as required.
For example, the Soviet 45-ton KV-1 heavy tank and 25-ton British Matilda II infantry tank were deployed at about the same time in 1940. These two models had similar levels of armour protection and mobility, but the KV's 76.2 mm main gun was much larger than the Matilda's 2-pounder (40 mm).
They were built for mixed-traffic duties, operating from 25 kV AC overhead lines and producing 5,000 bhp (3,700 kW). They weigh 84.5 tonnes and can typically achieve a top speed of 110 mph (177 km/h). [3] The Class 90 is a modernised derivative of the preceding Class 87 locomotive, having been originally designated as the Class 87/2.
The name WZ-551 actually covers two families of vehicles with the official designations in the People's Liberation Army (PLA) – Type 90 and Type 92. Over 3,000 WZ-551s are in service with the PLA, where they are used by medium mechanized infantry units.
The KV-13 (Russian: KB-13) was an experimental Soviet medium tank created during World War II. [ 1 ] [ 2 ] It was developed on the KV-1 chassis in the SKB-2 design bureau of the Chelyabinsk Kirov Plant in late 1941 – early 1942, as a "universal" tank , intended to replace the production of T-34 medium tanks and KV-1 heavy tanks at the same time.
