Google Rail: Going Nowhere Fast

This is why software engineers aren't allowed to do proper engineering

Or alternatively, that's why so much software doesn't work

Which wheels would need to touch to make it work? Unless the yellow wheel is entirely redundant and not connected to either of the lower wheels, it still won't work.

• The driving cog turns clockwise and turns the red cog anti-clockwise
• The red cog drives the left and middle wheels clockwise
• The wheels' cogs are double-thickness and the red/yellow cogs are in separate planes
• So the red cog drives the middle wheel clockwise, which in turn drives the yellow cog anti-clockwise, which finally turns the right wheel clockwise
• So all wheels turn clockwise on the rail, and in fact all 3 are geared equally

Someone check this please, I think it's sound though I doubt it is what the designer intended.

Maybe, but there's absolutely no sign of any valve-gear, unless there's some serious poppet-cam stuff going on between the frames - or any real connection between what seems to be the cylinders and the wheels.

Looks like it's been designed by a Bob, as there is also nowhere for the driver to sit.

The yellow wheel is an immobiliser.
