==German practice==
{{Main article|Bahnbetriebswerk}}

The equivalent of such depots in German-speaking countries is the ''[[Bahnbetriebswerk]]'' or ''Bw'' which has similar functions, with major repairs and overhauls being carried out at ''[[Ausbesserungswerke]]''. The number of these reduced drastically on the changeover from steam to diesel and electric traction and most modern ''Bw'' in Germany are specialised depots, often responsible for a single rail [[class (locomotive)|class]].

==Engine sheds in the steam era==
{{see also|Bahnbetriebswerk (steam locomotives)}}

Engine sheds could be found in many towns and cities, as well as in rural locations. They were built by the railway companies to provide accommodation for their locomotives that provided their local train services. Each engine shed would have an allocation of locomotives that would reflect the duties carried out by that depot. Most depots had a mixture of passenger, freight and shunting locomotives but some, such as [[Mexborough]], had predominantly freight locomotives reflecting the industrial nature of that area in South [[Yorkshire]]. Others, such as Kings Cross engine shed in London, predominantly provided locomotives for passenger workings.

Nearly all depots at this time had a number of shunting locomotives. Normally 0-4-0T or 0-6-0T tank engines, these would be allocated to shunt turns and could be found in goods yards, carriage sidings, goods depots and docks.

Many large rail connected industrial sites also had engine sheds, primarily using shunting locomotives.

===Design===

Each railway company had its own architectural design of engine shed, but there were three basic designs of shed:
* [[Railway roundhouse|Roundhouse]] - where the tracks would radiate from a [[Railway turntable|turntable]];
* Straight - a number of tracks that would be accessible from either end;
* Dead End - a number of sidings accessible from one end only.

The turntables for straight and dead end sheds were generally outside. Those in roundhouses could be inside, such as those at York in the UK, or outside, such as that at the [[East_Broad_Top_Railroad_and_Coal_Company|East Broad Top Railroad & Coal Company]] in [[Rockhill, Pennsylvania]], USA.

===Activity===

There were six primary activities that took place at the sheds.

====Ash removal====

When a steam engine arrived on shed, it would drop its fire and the ash that had built up would be removed. Disposal of the ash was a filthy job and carried out at quiet times, although some bigger depots had facilities for disposing of ash more efficiently. Study of photographs from the steam era show it was not uncommon for piles of ash to be scattered around the depot site.

====Boiler washout====

After completing their last duty and arriving on shed, locomotives would have a regular boiler washout to remove scale, improve efficiency and protect safety.<ref name="GER-Sheds-part1" />{{rp|31}}

====Coaling====

Locomotives generally ran on coal. Initially this job was done by hand and many depots had significant coal stacks on site. These would be neatly constructed with the outer walls constructed of dry blocks much in the style of a [[Dry stone|dry stone wall]] with smaller pieces behind these.<ref name="GER-Sheds-part2" />{{rp|222–3}} As technology advanced and the bigger sheds got busier, this process became mechanised and huge [[coaling tower]]s above the neighbourhoods indicated where the engine shed was. The sheds were not clean places to work. The large east London depot of [[Stratford TMD|Stratford]] had an engineman’s dormitory and its occupants would “wake up with a layer of coal dust covering them and the bed”.<ref name="GER-Sheds-part1" />{{rp|20}}

====Watering====

Another key requirement of the steam engine is a supply of water which is carried in the tenders or tanks of the engines. In Australia, water was also carried in water gins (a water tank mounted on a wagon) due to longer distances covered and scarcer water resources. In depots where the limescale content of water was high (known in some areas as ‘Hard Water), water softening plants were introduced. At Norwich engine shed in the UK, the sludge was discharged into a tank and emptied every three years or so with the sludge being dumped into the sea at Lowestoft.<ref name="GER-Sheds-part1" />{{rp|71}}

====Turning====

[[Tender (rail)|Tender]] locomotives required turning so they were facing the right way before their next duty. In the early days, these were typically around 45 feet long. As the technology improved and engines got bigger, then the [[Railway turntable|turntables]] got longer. In order to turn a locomotive the engine had to be balanced quite precisely on the turntable and it could then be literally pushed around.

Some turntables could be powered by fixing the vacuum brake of the engine to the turntable and using that to turn the engine.

Later turntables were electrically operated. Many diesel locomotives in the UK have a cab at each end removing the need for the turntables. However, in Australia and America, there are a number of single ended locomotives and turntables are still in use.

====Repairs====

Engine sheds would carry out basic maintenance and the bigger sheds would carry out more complex repairs. Locomotives that required further repair were sent to the company’s locomotive works. Withdrawn locomotives could often be found at some depots before their final trips to the scrapyard.

===Sub-shed===

In the UK, the general practice is that one shed would have a number of smaller sub-sheds where there were fewer facilities. When engines allocated to sub-sheds required repairs, they were often exchanged for a similar engine or perhaps just visiting the main depot on a Sunday when traffic levels were considerably lower.

In terms of locomotive allocation, it seems to have been the practice that for some railways locomotives were all allocated to the main shed but in others each shed had its specific allocation of locomotives.

A list of the British sub-sheds can be found [[List of British Railways shed codes|here]].

===Staff===
The drivers and fireman were the visible face of the engine shed and, as such, certain sheds had reputations for clean locomotives thanks to the dedication of those men. Many companies allocated a specific main line locomotive to a crew and they would usually take a personal interest in the cleanliness of their engine; some companies offered a prize to the crew of the best kept engine.

Many drivers would spend their own time on improving their knowledge and sharing best practice with younger drivers. The footplate staff (as drivers and fireman were known) were unionised from the 19th century and in the UK were generally in the [[Amalgamated Society of Railway Servants]] (later [[ASLEF]]) whilst other shed staff tended to be in the [[National Union of Railwaymen]].

Many engine shed workers put up with very poor conditions for many years. In the 1950s and 1960s, the rise of manufacturing industry saw many staff leaving the railway for better working conditions (and pay) and many railways started to modernise as a result.<ref name="GER-Sheds-part1" />

==Engine sheds in the modern era==

The maintenance of the new diesel locomotives in filthy steam sheds soon proved difficult and, although some old sheds survived, many new diesel depots were built on new sites or on the sites of the old steam sheds. The major problem was the disposal of oil, which initially was left lying around causing pollution and safety issues. The new depots were equipped to deal with diesel fuel and the ability to access the underside, as well as upper body work, was improved.

The tasks were not that much different in that diesel locomotives were fuelled rather than coaled, although they did require water as early diesels were equipped with steam generators for train heating purposes.

Since privatisation in the UK, some depots are now operated by the train builders who maintain the trains under contract with train operators.

==Stabling and fuelling points==
Around railway networks, there are locations just used for the coaling/fuelling of locomotives and the stabling of stock, either overnight or between duties. These are generally not regarded as engine sheds.
