London Transport Museum

This guide to the London Transport Museum follows Harry Beck, an out-of-work draughtsman who redesigned the Tube map in 1931 by abandoning geography altogether. It traces how his radical diagram was first rejected, then trialed, then adopted by London Underground's Publicity Office. Along the way it touches on the museum's Victorian flower-market building and its vintage trams, buses and Tube trains. Look for the original map itself on display as you listen.
