These could be swapped over ex-Camden so they are the other way round, but those are the 319 circuits this evening.
1739 ex Euston last night was 350 formed, 101 and 373 did the honours.
A pair of 319's will be out and about on Sunday due to an engineering block closing the line to/from Northampton. All Sunday services are formed with units ex-Bletchley because of this, including the 319's.
