Funny you say that actually...we wound up keeping the set with the Percy broken and spent two months hunting down another single train. You bet I was asked at least once a day if I had found a new one or not! And yes like you said they might send a voucher but it doesn't cover the entire cost or they want me to send it back and cover that cost as well...to be honest it sucks! And if they wanted to send me a new part I don't have any clue on how to fix it
