At the moment there are maps for rail and various other journeys from Cambridge. There is also a map for rail journeys from Edinburgh Waverley station. Very interesting, and potentially useful as well. It seems to suggest, though, that it takes longer than an hour to get from Edinburgh to Glasgow which is clearly not true.
It is shocking to discover that a huge chunk of the Borders — surrounded by lots of red zones — is completely inaccessible by rail plus an hour-long taxi journey. No wonder they are determined to re-open the Waverley line!
