There are regional variations in the UK albeit by only a tiny margin.
The Liverpool & Manchester 4' 8"
The London Tube 4' 8 3/8"
Uk Standard Guage 4' 8 1/2" (4' 8 " on tight curves)
and (I think) the Glasgopw Underground was 4' 7"
The Glasgow subway was 4ft, until modernisation when it was widened.
By 1mm. :-)
