Explanation of Shed Codes

Each engine was allocated to a home engine shed. This shed was where it was serviced and where it usually returned when it's duty cycle was completed. For freight engines a duty cycle was usually in one day. For express engines it could be several days, so an express engine may stay overnight at another shed.

Smaller sheds were known as sub-sheds. Leighton Buzzard was one such sub-shed, with it's parent shed being Bletchley.
