This is still really enjoyable and feeds my inner train-enrd and I like how changes in something like the rail network has changed British politics

Keep up the good work
@Devvy
Thanks, glad you enjoyed it!
I'd still think the Scottish government would have Edinburgh Waverley modernised for the commuter services and some of the intercity services
It'd probably be high up on the priority list, but money can only stretch so far, and Velocity will have taken a large chunk of the "rail investment" budget.
I thinking of starting a rail timeline about a high speed rail network between Scotland and Ireland
The cost will be horrific. Economics would suggest that a Liverpool-Holyhead-Dublin route would be best to be honest, but the tunneling would be horrendous (let alone the add-on tunneling to get a high speed route from Anglesey to England and on to the Velocity route!).
Scotland-Ireland is shorter, but has to contend with Beaufort's Dyke which is very deep and will be an absolute pain to get under. Also, high speed link through the Scottish Lowlands from the tunnel to Glasgow area will be more expense, and the potential market of Edinburgh-Glasgow-Belfast-Dublin is not massively high.
Scotland-Ireland is but a pipe dream alas!
So I guess for St Pancras its just the regular British costa,WHSmith and pumpkin cafe
WHSmiths, Boots, Costa, McDonalds, Burger King, Pret a Manger, and Yo Sushi!
....and a token pub somewhere....
WI would suggest that the E-G would have been upgraded for something like 100 MPH running as Devvy had IC ECML Services extend to GQS. The old Class 47 hauled push-pull sets were, IIRC cleared for up to 100 MPH running, even if the Duffs could only manage 95. Wouldn't take all that much to get the line up to 3 figures AFAIK.
Quite....I think something like this too.
