Collapsing Bridge

This is a collapsing bridge that is compatible with the Thomas wooden railway. Made this for my son for Christmas. I wanted to make him a bridge, but one that had moving parts (toys are always more fun if they have moving parts). Most of the bridges that move are a drawbridge type, in which the rail track moves up. This one collapses (I guess due to faulty workmanship). Little kids always like a disaster when playing.

Used a total of six magnets. It’ll remain in the upright condition no matter how many cars are on the bridge. Push on the dowel, and it’ll collapse. Pull back up on the dowel, and it’ll spring back into working condition.

Used bent lamination for the suspension. Birch, jatoba, and walnut were used.

Fun project to build.

Thanks for looking!

This is beautifull. Awesome design and fantastic execution. I bet that bridge will give him hours of fun and one day, when he has outgrown Thomas the Train, I bet he keeps that bridge.

I’m a little confused, was it supposed to be a draw bridge and the tracks move up? Even if so, it’s still very cool. Fine worksmanship.

Truly a design that understands its target audience. Nothing like a good bridge disaster on the railway to keep a boy entertained for hours. ;-) Nice work.

It’s supposed to collapse. Sorry if I made that unclear. Most of the bridges you buy are the drawbridge type. I wanted to build something different.

I love it! My kids are to old now, but I’m sure they would’ve enjoyed something like this when they played with Thomas the tank engine.
