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).

Out of curiosity, what would be the problem for the HSE here? Is it that
the different trains are sharing adjacent platforms? What about the
likes of Wimbledon where this already happens? What would be the
specific safety concerns?

Thanks, Dan
