Anyone know anything about the Tumbleweed Express? They say they are a "traveling railroad", and are doing Thomas events in Minnesota and Missouri. What equipment do they have?

Google knows almost everything..

Thanks, but unless Im just not finding it, there aren't really any answers about the train consist at that link. My son is getting old enough that he really knows the difference between railcars, and I don't want to take him and possibly disappoint him if it turns out to be a train of old Metra gallery cars.

Found out this is a Progressive Rail operation.
Found what they have for motive power: http://www.progressiverail.com/locomotives.html.
Anyone know what they have for passenger equipment?
