1459 on the 21a, will do the last short working from Middlesbrough to Thorpe Thewles at 1750
4045 on the 15
4046 on the X1/X2 (last one from Newcastle that runs all the way to Middlesbrough) replacing a late-running 1512 which in turn replaced that on the 28

1459 replaced 4062 which broke down in Deaf Hill I gather.
4045 presumably replaced one of the Centros on 15s.
