(29 Mar 2018, 6:19 pm)9920up wrote May changes to the 1B introduce extra evening running time. Thus the round trip to Crook will be over 2 hours so a different vehicle will be needed for each ex Darlington departure. Not clear where this will be from - no interworking pattern is clear. The last 1B to Faverdale seems to work off a 7 board.
The timetable then reverts back to normal from 3rd June...
Diversion somewhere maybe?
