In Harry Potter, Hogwart's students accessed the hidden platform to school, Platform 9¾, by running with their trolley full of luggage at full speed into the wall dividing Platform 9 and Platform 10.
At the actual station, Platform 9 and Platform 10 aren't adjacent (apparently J.K. Rowling got her platform numbers or train stations mixed up). But on a wall somewhere in between the two platforms, station management have put up a sign that says "Platform 9¾", with half a trolley protruding from the wall under it. The idea is, you can grab onto the handles of the trolley and pretend to run through the brick wall for a great photo op.
Well, here's our version...although I'm not sure my girlfriend is going to make it through, she's not running nearly fast enough.
