"Platforms to be not less than 6 feet wide"

The standard may have change during the past 150 years.

I may be wrong, but I doubt the original part of the platforms at
South Gyle are that wide, though the later extensions probably are.
The extensions are wider due to a change in the minimum width
requirements, but the extensions are at one end of the platforms
(the ends furthest from the main entrances and exits).

These platforms are dangerously narrow for the number of people
using them and a fair proportion of trains pass them at considerable
speed. If it wasn't for the huge railway cost increases since
privatisation I imagine they would have been widened by now.
