Tube quiz (40)
The problem: There are 11 tube lines in London. Your challenge is to identify a journey that travels along each of these 11 lines once, and travels exactly one station along each line.
Note: No walking from one station to another is permitted. You may not use transport other than these 11 lines (no buses, taxis, Thameslink, etc). After travelling one station along any line, you must change to another line. Assume Tottenham Court Road is open as normal.
Example: Start at Farringdon, travel on the Circle Line to King's Cross, travel on the Northern line to Euston, travel on the Victoria line to Warren Street... and now you're stuck because you've already travelled on both the lines passing through this station.
The solution: There are several ways to do it. Can you find one?
