The following Darlington services have variations registered, effective 27 September:
1, 3, 7, 8/8A, 9, 10, 17, 18/18A, 19, X66/X67
Includes the 17 being extended to Darlington Arena, 18 being merged with and replacing the 16 running from West Park to Harrowgate Hill (18A being an evening and Sunday variation which I think includes elements of the daytime 17 route) and the 19 being extended to Newton Aycliffe.
86/87 Darlington to Stockton via Stillington introduced, 27 September
28 & X2/X3/X3A also has variations, effective 27 September.
Whitby Park & Ride P1/P2 has a variation from 1 October before the 2026 season ends a month later.
