Two sets of train tickets, each of which are for specific booked East Coast trains between Newcastle and London this month. Both are sets of two singles, this being a far cheaper option than buying a return. Those on the left cost a total of £18.05, the ones on the right £172.25. The average cost per mile of rail travel might be the same as 1968, but the fare structure is many times more complex, and seems to be far less logical.
