It'll be over half a decade before the Crossrail project sees its first passenger services. But transport fans can now get a detailed peek at the route at New London Architecture. The Store Street museum-cum-showroom has long been one of our favourite places to casually drop by, thanks to its superb plastic model of London. This hobbyist's dream stretches from Kensington to City Airport, with a special flange for the Olympic site. Since our last visit, they've added the route Crossrail will take across the city, with some precision. It's fascinating (to a certain mindset) to see exactly which buildings the lines will pass under, and to speculate why it curves sharply in some places (existing tunnels? Deep building foundations? Nuclear bunker? Super-deep plague pit?). Check it out at 26 Store Street, just off Tottenham Court Road. Entrance is free.
