Hello , sorry I don't know about the Carlisle Railroad , BUT I have taken the train roundtrip a couple of times to Yorkshire from London and Wales. I just wanted to tell you to watch the movie about Yorkshire " Calendar Girls ". Beautiful scenery plus the story / people are real . The 2000 calendar was already sold out when I was there in Feb. and I really think you might get a chuckle or two.. At the time I knew they would make a movie about this story.
Also if you are able make it walking up the steps to the top of York Minster it's worth every step, if you can't at least TAKE YOUR TIME and go into the church to enjoy. Their is a tea shop right next to the church , also "Shambles area " TERRIFIC little shops with ancient historical buildings. Walk the walls are a must , Roman areas where soldiers are buried are right in the area - walking distance. Don't forget to try Yorkshire Pudding ! We stayed a B&B's two different times then once at York University Dorms as I was there for a Genealogy Conference. Some do take the train to Scarborough , I think a castle there.. you'll have to google.. If you could hire a driver there is wonderful Cistercian , Rievaulx Abbey in Helmsley in North Yorkshire Moors. Directly across the road alongside the Abby is a beautiful stone thatch cottage " how old , it's OLD " , artist travel here from all over the world to paint this cottage. If I knew how I would post a picture of it.. Anyway I hope you have a great trip, would love to go back again .. can't you tell !
