or railroad truck
is a structure underneath a train
to which wheel
axles (and, hence, wheels) are attached. If they are used there are two for each carriage
, wagon and locomotive
, or alternatively, they are at the connections between the carriages or wagons. The connections of the bogies with the cars allow a small rotational movement around a vertical axis.
Usually the train floor is at a level above the bogies. However, for a double decker this applies only at the bogies: between them the bottom deck is lower.
There are low-floor trams without bogies.
- To be explained: notations such as 3-4-3, Bo-Bo and Co-Co.

In the military, a bogie (or bogey) is an unidentified object, usually aerial. If the bogie turns out to be an enemy aircraft, it is then called a bandit.
Bogie is a nickname for the actor Humphrey Bogart.
Bogies (singular bogy) are ghosts, or pieces of nasal mucus (see snot).
