Does your commuting train make moaning noise?

I think all the overtime work I did, finally getting me.

Last few days I started to notice my commuter train makes some kind of metal bending/yanking weird noises that oddly resemble women moaning. I’m talking the moaning noise you hear from your upstairs neighbor, kind of moaning.

I’m not asking for help or anything. Just got curious if others have weird stories like mine.
