Not sure if you can leave the train and take another one later from St. Thomas. The train makes a stop for ten minutes, which is halfway, but just for visiting some old train parked on the other track. Better to check with them before buying the tickets. Food is good and plenty of places to choose from. I had breakfast at " That Breakfast place". Was ok. Nothing special. And a late lunch at "Buccaneers " (located next to the main beach) which was very satisfying and fresh. I recommend the local fish(yellow perch, pickerel). The ice team at "Broderick's" was ok. Large scoops though. Try the homemade chocolate dip con. As per places to see, I couldn't tell you mach, as i was there only for one day and mainly for the beach. Which is amazing!! But they have some art to visit and some antique shops. It is a nice town to spend a day. Hope it helped
