What it does

A dog bone shaped connector sized for tracks with bigger holes
Shaped to join two wood-style track pieces end to end
Wood-style look, so it blends in with your existing track set
Made for BRIO, Thomas, and IKEA wooden train tracks
Made to order in the USA after you place your order

Inside a busy playroom, train tracks spread across the floor in every direction. This dog bone connector gives you a piece shaped to join two wood-style track sections end to end, so the layout can stretch further.

It has the bone shape used for track pieces with bigger holes, made to match tracks from BRIO, Thomas, and IKEA wooden train sets. The piece carries a wood-style look, though it is a printed part and not made of actual wood.

This connector is made to order in the USA after you place your order. It is not affiliated with or endorsed by BRIO, Thomas and Friends, or IKEA. Check your existing track's hole size against the big bone shape before you order.
