Portsmouth-Waterloo via Haslemere was never IC, as wasn't Dover/Ramsgate etc-London...
Wasn't there a thing called InterCity Shuttle at one point? I think it covered Nottingham, Derby, the Towns Line as far as Retford and the GWML to Bristol, effectively a 125 mph commuter service.
What's the furthest you can get from London in 60 mins. The fastest I can find for Grantham is 61 mins to that's out. Peterborough is about 76 miles. Maybe there is a longer commute (<1hr).
Yes, there are, and I'm aquainted with quite a few of them - as are some on-board rail staff!I know a lot of people "commute" between :
Newcastle - Kings Cross
Interestingly, I beleive only a very few do that as a "commute". The MP for example. But many Berwick professionals are more strongly tied into Edinburgh (and public service under Scottish Law) so don't have the same need to be in London as some from elsewhere in England.If the definition of 'commuter' line is one where a season ticket can be purchased (not the ALR) then I think Berwick>Kings Cross is about the longest; it's electified too!!
I was going to suggest the Thameslink route, at 140 miles and it would hard to rule that it is not primarily a commuter route (though, more like 2 joined together though!)
In my line of work I think our furthest 'commuter' lives in Auckland. No season tickets though!
