Guests who take a ride on "Mark Train's Gold Rush Adventure" will exit the ride through "Mark Train's Railroad Mercantile". This store will sell all manner of things related to trains including electric train sets, train posters, train DVDs, train music CDs, train whistles, train jigsaw puzzels, as well as engineer's hats, overalls, and clothing items that promote the ride... "Mark Train's Gold Rush Adventure." We also have some ideas for in-store photo opportunities, and electronic arcade games that relate directly to the ride itself, or... trains in general.
