Bletchley loco stabling sidings 1983-2004

Lines of class 25 (rats) or 31’s (goyles) stabled at Bletchley Field/Holding sidings were a familiar site to us all. Before late 1983 it was a virtual class 25

monopoly on the Field sidings, apart from the 08 pilot. The class 31 encroachment then set in and by 1987 our “rats” were no more. The late 80’s saw the traffic

worked by the Bletchley locos and crews steadily decline and by the mid 90’s it became rare to see loco stabled in the “Field Sidings”.

On the wonderful fully privatised WCML, locos did return to the Field Sidings with Virgin “thunderbirds” stabled on occasions. By 2007 these duties had ceased with

a Rugby “Thunderbird” providing cover. Track alterations with the closure of Bletchley PSB saw the Field sidings ripped up in 2012 leaving a single “hopper siding”

for the stone train, stabled locos no more……………….


Sample 1980’s Bletchley loco turns


1/  Tring - Kings X cements

2/ Forders - Kings X “brickies” (Fletliner)

3/ Hartshill - Nuneaton - Bletchley/Willesden ballast

4/ Bletchley - Akeman “UKF” trip

5/ Parcels traffic to Aylesbury/Bedford/Euston/Northampton

6/ Engineers turns from a single crane to the BY wiring train

7/ Drags due ole isolations, especially emergency isolations

8/ Failures - DMU assists on the Bedford - Bletchley

                   Disabled electric loco assists to Euston and beyond!


Initially the surviving work was lost to various London and Rugby “depots” but with privatisation most turns were lost to rail traffic, such is progress…


Sample power  April 24th 1982


The amount of power stabled at Bletchley varied by day and time. 2 sizeable lines of stabled “rats” greeted me late on Saturday 24th April 1982 prior to these fine machines taking up engineer’s turns. Bletchley “Field Sidings” that evening had 08374, 25027, 25168, 25181, 25248, 25288, 25289, 25296, 25317, 25319  all stabled in the gloom. A fine collection of “small Sulzers”
