The same with Bicester-Bletchley, any remnants of old stations etc were obliterated.
Actually got me thinking what physical infrastructure (Platforms/Station buildings) will be left on the Portishead Branch.
Ashton Signal Box - demo'd early 1990s?
Ashton Gate Station - Platforms remain
Clifton Bridge Station - Platforms & Bridge remain
Nightingale Valley Halt - Nothing remains
Ham Green Halt - Platform remain
Pill Station - Signal box demolished in 1964, Street level buildings due for demo by end of year, coal sidings removed in 2000 prior to freight reopening.
Portbury Shipyard - Nothing remains.
Portbury Station - platform & station now private residence.
Portishead Station(s) - Pier station building demo'd for RNLI 2015, Original station demo' 1954, Second Station closed 1964, used as part of petrol station till Waitrose? circa 2000.
So the demo of the Pill buildings will leave pretty much just a few platforms and Portbury station as the only remements of the original line operation.
