Will Walkergate be loaning out E400s to other depots during the closure of all educational institutions, which is what usually happens during the summer?

As all school, colleges and universities may be closed until at least the beginning of May.

According to bus times, the buses now swapped between Sunderland and Slatyford are 36091-94 and 36960/1/3/4 with just 39724/25 left to be transferred to Sunderland. If 39724 is broken beyond repair, will Slatyford be sending another vehicle to Sunderland?

Are any other vehicle swaps at Slatyford planned?
