Scania 5213 has encountered a problem of some sort whilst on service 20 - taken out of service on Durham Rd, Sunderland, with all passengers moved onto the following 20A (5212).

Was able to head back to the depot under its own power, suggesting that it wasn't a breakdown and was in fact another problem.

Means that there will be two 'odd' workings on the Prince Bishops today - another covering for 5216 which was not allocated at start of service.
