jernbanedepot

A jernbanedepot is a railway facility used for the storage, maintenance, and servicing of rolling stock, including locomotives, passenger cars, and freight wagons. Depots may be dedicated to propulsion units, carriages, or combinations, and they provide space for lodging of trains when not in service as well as routine and major maintenance work. Typical activities include inspections, wheel maintenance and profiling, component replacement, cleaning, fueling or charging of traction batteries, and light or heavy repairs. Depots are supported by workshops, inspection pits, lifting and testing equipment, cranes, track maintenance facilities, and sometimes on-site wash plants.

Location and organization: They are usually located adjacent to or integrated with railway corridors to minimize deadhead travel and enable efficient rostering. They are owned and operated by railways or infrastructure managers, and their operation is governed by safety, environmental, and railway standards. Scheduling, staff rosters, and dispatch coordination are part of depot operations.

Types and terminology: In different systems, depots may be referred to as locomotive depots, traction sheds, maintenance depots, or stabling yards. Some facilities are specialized for electric traction with overhead lines, while others are tailored for diesel or dual-mode fleets. Modern depots may incorporate automated bogie exchanges, wheel lathes, and non-destructive testing equipment.

History and scope: Depots began in the 19th century to support expanding rail networks and have evolved with the shift to electric and diesel traction and more diverse service patterns. Today they are essential components of rail operations, enabling reliability, safety, and efficiency across passenger and freight networks.
