Is it actually possible to get to the platform at Liverpool Street Station without having to carry your bike down the stairs, or use an escalator? (The escalator probably being a bit dodgy with a bike). I guess there are lifts somewhere, but is there actually some way to walk in, and just be at the correct level? When I popped in there to pick up some tickets, I asked one of the bright yellow "customer advisers", who couldn't come up with a suggestion.
