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.
Because they are driving on privately owned land in many jurisdictions a full bus licence may not be required to perform such tasks.
Central works have declined with increase in sub-contract engineering, and improvements in mechanical reliability of bus designs.
Also, the practice of routine mid-life refurbishment of bus fleets has declined, which has resulted in generally shorter service lives.
Bus garages will generally have large areas unobstructed by supporting columns as well as high roofs, especially for storage of double-decker buses.
