We took our nephew and niece there yesterday. Their family rode the train, the rest of us didn't but there was plenty to do. The RRHS in Medina did a fantastic job and the Thomas crew were very pleased with the turnout and the way things were organized. One of the crew said that all the trains were sold out in advance - 20,000 tickets. People came from as far away as Ohio, North Carolina, Tenessee, and even Europe (Nove Scotia).
They had entertainment for the kids when they weren't on the train, and for the big kids the freight station which houses the RRHS was a class act in how to build a RR museum from a RR station; beautiful restoration of period office display, a huge model layout, and walls lined with antique models and RR stuff. The two items that stood out was the pristine 1898 NYO&W timetable and the G scale PRR T-1, obviously a custom job ("Rickard" badge on the boiler).
Alco U420 was the power for the Thomas train.
If anybody missed it, take your kids next year.
