That's even better than the "15 minute" frequency now advertised for the 22/24 between them. They share about 5 miles in common at most - Durham through Leazes road and Gilesgate, plus a bit of the Shotton Colliery - Peterlee run. The rest is completely different and the buses go in opposite directions after Peterlee.
