if they ever extend it to Highgate highlevel via finsbury park and the
parklandwalk then one island platform and standing in the rain without a
roof ,will do me...... but then again at highgate highlevel they is already
a platform and 1930 waiting room biult for the extention and hardly used

That'll never happen. Aside from the fact that they'd have to build a whole
new flyover at finsbury park can you imagine the Nimby factor in Crouch End
when all the yoghurt knitting right-ons in the area find out that their
tranquil woodland path nearby is going to be converted back into a railway.
Also the logical conclusion would be to terminate the line in the middle
platforms at east finchley but then the HSE would start to wet themselves
about having tube and mainline trains in the same vacinity so that probably
wouldn't be allowed (much safer to allow people to travel by road to Highgate
obviously).
