This would be interesting ride:
BBC News - Mail Rail: What is it like on the 'secret' Tube?
This is very interesting. I would never have guessed such a thing existed. Very well kept secret I would say. Might be worth a ride though if nothing but for history preservation. Thanks sg1974 for the post and the enlightenment regarding London's Mail Rail.
it has been approved, but no need to rush as it won't be open till 2020.
BBC News - Plans approved to open Mail Rail 'secret Tube' as ride
hope to be there when it opens.
