I agree the migration lists are well out of date now. Yes it is happening but no where near the speed that they first suggested. Half of my signalling centre was due to close by August 2017 by the original plans 5 or 6 years ago. Now we are nearly there, there isn't even any plans on the drawing board yet let alone the funding for it. But we are due to get TMS isolated wishin the next 18 months attached to our panels so read into that what you will.
So yes the plans are going forward at a much slower pace. Any location that closes will have displacement and relocation packages as agreed by your Area/Route council Reps to a formula that had been agreed nationally. The way to find out who your Area/Route Council reps is via your Local LDC rep who deals with your LOM on all local issues on your behalf.
If you can get hold of copies of the 1994 agreement, 2001 agreement, National Rostering Principles, The Conditions of service Green Book (April 1997) and the PTR&R (Promotion, Transfer, Resettlement & Redundancy) 1985 which in particular covers the two R&Rs. These cover most but not all of the agreements that the Union and company have. Even if you only join the Union just for legal protection like most do, get to know you local rep well and milk them for all the information you can from those publications amongst others.
