Ormskirk to Blackpool South, BPS to Colne and Colne to Ormskirk were de facto through workings although shown on timetables as terminating at Preston. Is this still the method of working? The 1655 Carmarthen to Manchester Picc and 2214 MAN to Chester is the same train.The obvious ones are where it’s a de facto through working. Can’t give specific examples but there have been plenty on here in the past.
