@nprofile1q... Yes! Penzance today, I may try to visit the communications museum in Porthcurno tomorrow, and then back-tracking to Bath to stay for a few days. I had hoped to take the ferry out to the Scillies, but they are only doing one run a day in each direction at this season, and it's all booked up with early tourists.
Thursday night and Friday I spent in Thurso, before taking the Caledonian Sleeper from Inverness to London, so I've done both British sleeper trains in a weekend.
