In which case there's a good argument for some extra stops!I use the 1630 often, it only calls at Preston.
I'd personally recommend it... it's not that heavily loaded. I never have a reservation and easily always get a 4 seats-to-a-table space all the way from London to Glasgow.
I agree, it's practically empty after Preston, and is within a cluster of trains during an hour period that head up to Scotland. At least Carlisle should be added, maybe Motherwell, and one of the three between Preston and Carlisle, most likely Lancaster. Then again that would destroy the headline time, so it's a no-no, despite how effectively useless it is.In which case there's a good argument for some extra stops!
