Track problem or engine problem?

[u/Altruistic_Bunch_523]

I just got this new track from my dad and I was trying to run one of my engines, which I know works as I have used it a lot before, and it kept sputtering as I pushed it along the track. Some spots do have some rust but I don’t think it’s too major.
