Cave splines or assets [TANE]

This is something I've been wondering lately. Since I know Modula City has like a cave system and such, is there any assets or splines that I can download and would make a perfect cave system for a Trainz route? Reason I'm asking is because I am thinking of adding some kind of cave system to my fantasy Trainz route that is a WIP and I'm thinking of having maybe a railroad line running through it. Any tips or advice would be greatly appreciated.

Shortline2 did a cave series I believe but it is 18" gauge I think.

It's on the Download Station I'm guessing and what is the Kuid?
