Indeed it is - sadly not on either board that does the peak 5As nor the one that does the X66 tonight. 1470 replaced it on the 5 at 1350 and it appears to have been sent out more-or-less straight away onto the 9/27/27a.
EDIT: more details - there was a beer spillage on 1556 so to make sure the 5 left on time, 1470 was swapped onto the 5 off the 9/27, then once cleaned 1556 went out on the towns.
