Tend to agree with this; very illogical numbering for a non enthusiast and I can see why people get caught out. Not even just the same island/stairs, pretty much every other station in the UK I can think of its the same actual platform! (the suffix letter variants are simply sub sections of the main numbered platform - Brum New St, Leeds, Reading etc.).
Can anyone think of any other UK examples where this isnt the case?
Good non UK example I learnt to my cost is Roma Termini, where 2Est is a VERY long way from platform 2...
I nominate Stratford, jointly with Edinburgh Waverley, as the most confusing platform numbering in the UK.
Europe, plenty of oddities. My favourite (albeit on a much smaller scale) is St Pierre Des Corps which has 4 main platforms, numbered (South to North) 1, Z, 2, 6. (with a West facing bay platform 4) Must have made sense to someone at one point.
