1430 and 1432 are short term cover, as originally the Durham EV double deckers were due to be in service well before the P&R season started.
Due to delays, this is unlikely to be the case, so these two have been earmarked for very short term cover to allow the MMC's to go to Whitby in time.

I'd expect the two MMC's to come out of Durham in Feb/March time for repaint, ready for 29 March start on the P&R.
