Visual Description

Steam locomotive combines the steamy industrial era of progress with the typical Ugears fleur. A definitive Kickstarter hit— this locomotive is made to look like real engines of 19th century. The only thing that lacks is the actual steam — the feeling of railroad romance is definitely there.

The design is stunning and the attention to detail is amazing: detailed engineer’s cab with retractable step ladder, art-deco boiler trim, and open-up Tender with coal — all these have moving parts and add a realism feel to every step of the assembly and play.

Main Features

The locomotive is powered by a rubber band engine that actually looks and feels like a real steam one. Upon closer look-up you will be able to see the movement of asynchronous pistons at the front of the locomotive that transfers the power to the wheels using a complex system of rods, linkages and cranks.

Comparison with Prime Steam Express by RORK

Prime Steam Express Model Wooden 3D Puzzle by ROKR

Ugears locomotive is definitely winning in terms of functionality. The wind up mechanism and the tracks are a great way to play and have limitless fun value. As for the design, Ugears 3D wooden puzzle has a simplistic design whereas the Prime Steam Express has way more cool digitalisation features and is basically a model for display, not for playing.


It is quite complex puzzle that will take you a weekend (or even a few) to assemble. The coolest thing is actually seeing how it moves on the rails and realizing that you have assembled that yourself without any additional instruments — only by following the instructions.

A great puzzle that gives that pleasant sense of achievement in the end.
