I was reading a book by Brian Hardy about the tube trains on the Isle of
Wight and he states that the LUL track gauge is 4 foot 8.75 inches but the
BR gauge is 4 ft 8.5 and that this caused issues initially.

The issue I read of, I don't know how far true though, was that the
Standard stock's hardened steel tyres wore the rails down excessivly
fast when they first went to the IoW.
