Bought to connect to Sodor shipping load and go take and play set which is a really excellent toy loved by my 2.5yr old daughter. The engine wash set is a good addition to extend the track but would I imagine be a bit boring on its own. My daughter finds it difficult to get some of her other engines to move through the wash, some don't fit very well e.g. Emily and James are a bit tall, although the Percy engine which comes with the wash play set goes through ok, the button on the top of the wash can be difficult sometimes as you have to press it firmly then release several times to get the momentum. That said it doesn't bother her and she can get her hand in the other end of the wash to pull any stuck engines out!
