Four signalling changes - but can you identify the year? One each, initially, please.
1. Marmalade the cat transferred from Brewery Sidings to Diggle Junction in connection with his being made redundant under the Manchester North resignalling
2. The hydraulically operated gates at Brigg (the last in the country) are to be replaced by barriers controlled from the existing signal box.
3. Bo-peep Junction to be abolished, area to be controlled from South Kent (Ashford).
4. Tondu box to close, area to be controlled from South Wales Regional Operations Centre at Cardiff.
https://signalbox.org/section-c/alterations-1998/ and its brothers are fascinating pages.
Marmalade - 1998
Brigg - yet to be answered
Bo-Peep indeed has not happened yet and there is a date there in the future
Tondu indeed listed for this year (2023)
