Engineering works - railway engineering works

Background:

This profile covers the processes and activities carried out at railway engineering works. The works covered by this profile are generally referred to as heavy maintenance depots. This profile also includes the processes and activities carried out at refuelling yards.

Potential Processes and Operations:

Railway works have been involved in the manufacture and repair of locomotives, carriages and rolling stock. The buildings range in size from small engine sheds, where only minimal maintenance is undertaken, to large-scale manufacturing works, where construction of engines, carriages and rolling stock and a full range of maintenance and refuelling operations takes place. Many sites have their own electrical generation facilities and there could be water pre-treatment facilities in areas where water is particularly hard. Larger works may have incorporated steelworks and gas works.
