Need a Trackmaster 'Arry chassis.

Yeah I found out the hard way haha.

 

I am not for sure but wouldn't any chassis from the Diesel line work? There are several iterations. Hopefully some of our experts will be along shortly to let us know.

Hmmm...my brain is telling me something about a Muddy Poppins video...can anyone help out my little brain?

BTW: Welcome to the Posting ranks here at BPT's Culdee04

The TOMY won't work due to the size I believe, trust me I found out the hard way haha.

I guess ones from HiT Toys onwards would have to do. Where to find one? Hmmm...
