I suspect that it may have been a convention between the railway companies rather than a BoT rule. I think the main platforms at York were built to this "standard" and have never been raised. (I don't have a reference for this to hand; will search tonight).
Digest 62.0 also states that "The ends of platforms other, of course, than of terminal platforms off a concourse must have a ramp, steps are not acceptable ... ". This was doubtless an actual rule for many years but seems to have been changed recently. The new (21st-century) platform at Cambridge, for example, has steps and no ramps.
