Got this for my son. He has some of the sets but they dont come with any extra track so this should do the job. Its been reduced from 10.99.
Amazon also have Diecast Chuggington Repair Shed Playset with Brewster
for 12.21 reduced from 26.99. The reviews for this arent great but my son enjoys playing with the other sets he has so this will makea nice addition.
