I had not been on a train tour here in US nor Canada. We went on a 3 week vacation to Canada last summer and we always get Grayline tours which is always organized. We do it here in US too. We had tried Europe where you stop in a city then get hooked with a tour Co. It is always good to plan ahead of time with accommodations first then the tours. good luck to you. Bellie
I've traveled with Great Rail Journeys, a British tour company that organizes rail tours world-wide. They offer some North American tours, but the one I took was from London, England, to Lake Como in Italy. It was a well-organized tour, and we traveled 1st class on some excellent trains, but since there were 40 people in the group the accommodation was in large, somewhat impersonal hotels.
I've also taken some solo rail vacations in Italy, which is easy to get around by train. From Genoa you can travel west along the coast to France. Milan is a good rail hub for exploring Northern Italy. Rome and Florence are connected by fast trains. Buses also go everywhere, so if there's a rail strike you won't be stranded.
