Hi guys

I've looked around for an answer to this, but haven't found a solution. Sorry in advance if it's a simple question, but it's my first train.

I have noticed that my loco makes a clicking noose everytime the front or rear trucks go over the points at which the track connects. It's quite loud and distracting, and I was hoping there might be a way to fix it.

I was considering taking it apart to see if there was something I could do but I'm not sure what the fix would be. any assistance you can provide would be greatly appreciated
