At the website that Rick Steves recommends for checking train times.
If you search a train and it says change does that mean your physically have to get up and find another train or is your cart simply pulled again from the station by another train. I notice that some of the trains I search said 45 minutes transfer. I assumed that meanst I had to get off the train and get on another. Other searches just said I had to make a change. But I am not sure if I just stay on my car and wait for another train to pull me away or if I have to physically get up find a new train and board? Any clarificaton on this would be helpful.
