You may be very surprised at the number of business commuters living around Doncaster (because of the rail link) using the train daily to the City, but also taking weekly journeys north of the Border. For Edinburgh that's fine but For Glasgow it's either a night out or a flight from EMA or LBA to get a job done in a day. It's more than frustrating for it to take over an hour to get to and from either with current traffic volumes on the M1 & M62
