I recently purchased a Lionel Dodge Track inspection truck 6-18438 at a train show. It was new in the box for $25. Good deal! I thought.....

So I finally got a chance to try it out after a few weeks, and it does not work. It seems whenever I set it on the track nothing happens. When I push it or move it a bit, then it might work a little. I have to "twist" it between the rails to get some type of connection or movement. By twisting it, I mean that it's setting on the track, then from above I grab it, and turn left or right to get a little movement.

Does anyone know what may be the issue or can point me in the right direction?

Thanks in advance!
