Hi ! I'll be staying in Falkirk for 4 days (from the 18 to 22 of april) and I wanted to visit Glasgow and Edinburgh (one day for one city) and maybe go to Alnwick which I know is not in Scotland. My question is : where do I buy a train ticket, which one, on what site do I buy it. It has to be a ticket that I can use from Falkirk obviously. And as on my last day I'm going to Alnwick castle, I believe I have to buy a different ticket right ? I don't have a driving licence so the train is my only option. Thanks for your answers.
