My favourite train trip had a Stranraer connection. I had been shortlisted for a graduate civil engineering sandwich placement with BR in February 1982 and was provided with a cardboard return ticket from Belfast York Road to London Euston to attend an interview.
The ticket included the Larne-Stranraer Sealink ferry trip and I made it as far as Carlisle before the trip went awry. The overhead wires were down in Cumbria and the London bound train was delayed. I spotted a train with aircon coaches that looked like it was departing, asked a BR person if it was going to London and jumped aboard when told yes.
The train pulled out heading south and duly followed the Settle and Carlisle route - spectacular in clear blue skies and recent snowfall. We eventually arrived at Hellifield and stopped for a time before heading to Preston via Clitheroe. We pulled into Preston in the darkness (I had left York Road at 06.30 ish) and then headed south, arriving at Euston at 9pm.
I didn’t get the BR job but enjoyed the train trip.
My next and most recent trip over the Settle and Carlisle was in 1985 behind Lord Nelson and Flying Scotsman.
Cheers
