A bus garage, also known as a bus depot, bus base or bus barn, is a facility where buses are stored and maintained. In many conurbations, bus garages are on the site of former car barns or tram sheds, where trams (streetcars) were stored, and the operation transferred to buses. In other areas, garages were built to replace horse-bus yards or on virgin sites when populations were not as high as now.
The largest bus depot in the world is Millennium Park Bus Depot In Delhi India.
Most bus garages will contain the following elements:
Smaller garages may contain the minimum engineering facilities, restricted to light servicing capabilities only. Garages may also contain recovery vehicles, often converted buses, although their incidence has declined with the use of contractors to recover break-downs, and the increase in reliability.
Overnight, the more valuable or regularly in-service buses will usually be stored in the interior of the garage, with less used or older service vehicles, and vehicles withdrawn for storage or awaiting disposal, stored externally. During the day, internal and external areas will see a variety of movements. Heritage vehicles are almost exclusively stored inside the garage.
