Well, it was during the 1980s, if we are talking about the Western Region of BR. I was working for the Reading Division in Western Tower Reading. It happened over a weekend when we went fully fitted. l also recall they managed to leave a train of unfitted wagons in Woodborough loop and I never found out how they managed to get them out again.
There was a series of sprung catch points on the B&H between Lavington and Newbury, whose decommissioning I'm trying to date.
All the catch points on that section of line were put out of use at 0800 hours on Monday, 16th May 1983.
