This is a very interesting shunter from Tomix. The wheel arrangement is very unusual and also the size of the shunter itself. Despite it’s small size, this shunter is no softie. It can pull what your mainline loco can pull and maybe even abit more. I think this is because of the strong motor and alot of help from traction tyres.
Here’s a tip, if you are planning to remove the body, make sure you do in a plastic bag because a tiny spring pops out of no where. As you can see, one side doesnt have the coupler anymore because i lost my spring.
