Urgent request for information on Redbridge, Track & Sleeper Depot.
By Mick House.
So I am looking for someone that worked on site or with knowledge of the site to help me out.
If you can drop me an email at: email@example.com
R (Chacewater, repeater for signal 100. The IBS home was C100)
Back in the 1950s, only colour lights carried identity plates and usually only IBS signals. Treverrin IBS between Par and Lostwithiel was just like Baldhu: the signals were P100 and L100 etc.
At Baldhu, the down IBS was controlled by Penwithers Junction (PJ). See photo of PJ on website! This IBS is still there, but controlled by Truro since 1971 (T45 & T45R).
Today you will find these plates on several Cornish boxes: P, PR, LL etc.
Many thanks indeed Roy.
To add to the comments about the ‘C’ plate at Chacewater......
If my recollection is correct, the need to add ID plates to signals came about with the use of signals at locations remote from their controlling signal-box, hence the initial uses being mainly at IBS signals. The idea arose because of the need for the driver of a train held at a ‘remote’ signal to know by which box that signal was controlled, once it was no longer possible for him just to look out of his cab and see the box in the distance.
In a similar vein, once large areas of complex junctions and sidings etc started to be controlled remotely from a ‘power box’, then it became essential for drivers and signalmen - when communicating over the telephone - to have the correct understanding of exactly where they were. In the absence of the former signal-boxes with their nameboards, new nameplates had to be erected at the lineside to identify each junction etc.
Thank you Chris, you concur on Roy's comments.
