LOCOMOTIVE WHEEL ARRANGEMENT
2-(2-2)-0
Under the Whyte notation for the classification of steam locomotives, 2-2-2-0 usually represents the wheel arrangement of two leading wheels on one axle, four powered but uncoupled driving wheels on two axles, and no trailing wheels, but can also be used to represent two sets of leading wheels (not in a bogie truck) two driving wheels, and no trailing wheels. Some authorities place brackets around the duplicated but uncoupled wheels, creating a notation 2-(2-2)-0, or (2-2)-2-0,Baxter, pp.

Tupolev TB-3
The Tupolev TB-3 (Russian: Тяжёлый Бомбардировщик, Tyazhyolyy Bombardirovshchik, Heavy Bomber, civilian designation ANT-6) was a monoplane heavy bomber deployed by the Soviet Air Force in the 1930s and used during the early years of World War II. It was the world's first cantilever wing four-engine heavy bomber. Despite obsolescence and being officially withdrawn from service in 1939, the TB-3 performed bomber and transport duties throughout much of World War II. The TB-3 also saw combat as a Zveno project fighter mothership and as a light tank transport.
