I travelled on the West Coast Main Line south of Stoke.
Every now and again there were a line of posts on each side of the track - they were t-shaped and on the cross bar there were a large number of squares-either sensors or number indicators - there might have been about 10 in a row.
After a while, they seem to be where there were track crossovers.
Can anyone explain what they are where I can find out more.
