We walked among the big trains, climbed aboard a few, and took a ride on the little replica train, twice around the track encircling the park.
Two would for comfortably in the seat, with a kid on a lap. Our kid insisted on sitting between us, and took great delight in waving his arms, thrashing his head side to side (into my boob. Umm... Ouch) and giggling.
These photos are the best present any Auntie could ask for.
