The Experimental Engines Yard Chassis

The Experimental Engines Yard contains a small four-wheeled chassis. The chassis has a cog-driven system similar to Theo's, albeit with the cogs being separate to the wheels, which are driven by outside cylinders. A vertical boiler is also mounted on top. Despite this, it does not appear to be able to move around under its own power and usually has to be pushed around.

Basis
The cog machine has no known basis.

Livery
The cog machine is painted black all over, with grey wheels and red cogs.
