That’s very good news. There’s a bit more involved at Ormskirk than just removing the buffer stops but the lack of need to recharge at Preston will strengthen the business case.
Though we still need to be very, very, very careful about the risk of importing delays from the likes of Castlefield (which is why Merseyrail
isn't the solution for the CLC).
Preston once an hour would probably be fine, though, or as an initial step move the buffer stops to Burscough Junction, as that'd be less complex in signalling terms, and Burscough does these days have plenty of demand, having had lots of new homes added recently - really it's the new edge of the Liverpool conurbation in a way Ormskirk was years ago. That would also allow a unit to be taken out of the Blackpool/Ormskirk/Colne circuit without cutting services.
I'd also look at Wigan Wallgate sooner rather than later, as it might be easier to just build Headbolt Lane as a through station with a bridge with lifts if that was going to happen soon, and save the cost of building the separate Wigan platform.
