What I mean by keeping the mumbering is to keep with the sequence, so after 594 its only logical to continue on from 595 to 599, still I do think that Metro should have kept the Hebden Bridger map inside the timetable so that it would help people understand the changes.
Sorry, but I disagree about introducing the 595-599 numbering.
Routes 590 & 592 are now used for the increased through service from Halifax through the Calder Valley to Hebden Bridge, Todmorden, Burnley/Rochdale, and a numbering in that sequence could suggest the Heptonstall and Old Town services are also through from Halifax, as indeed some were until First withdrew them in order to provide a more frequent service along the main trunk route to Todmorden.
The old system of A-E made it clearer that a change of buses was required in Hebden Bridge - ironically something about which I gather the residents of Heptonstall and Old Town are now unhappy.
I do agree, though, that keeping the old Hebden Bridger map inside the new timetables would have been useful, but I suppose when it was planned that TLC would take-over the local Hebden Bridge routes there was uncertainty as to whether through fares from Halifax, etc, would still be available.
