I expect further changes to the list!
And it did later become a bit less impossible, at least:
17:20 Reading to Redhill due 18:55
18:59 Redhill to Reading due 20:35
But someone's having a bit of fun filling in the explanations (delay attribution codes). The last train back from Redhill shows as:
This service was cancelled due to late arrival of an inbound service (YI)Which is odd, as that "inbound service", arriving at 18:55, was cancelled:
This service was cancelled due to a problem at the depot (MU▸ ).The earlier ones are all listed as:
This service was cancelled due to the planned train being replaced with a slower train (MS).The DAPR puts that differently, without really explaining how it could make any sense here:
MS: Planned underpowered or shortformed service and or vehicle, incl. exam set swaps (abbreviation: ALOC STOCK)
