Rideable spline blueprint?

Hi, I’m currently working on a project that involves a rideable spline,
to give background, I’m a level designer with no experience in coding or blueprints at all,

the project itself is based on Bioshock Infinite and I am looking to know how to make a rideable spline like in this clip
of the demo here BioShock: Infinite E3 2011 Gameplay Demo (PS3, Xbox 360) - YouTube .

what I would need of it is attaching, detaching, jumping to another existing line and having a sprite show where I’m going to connect and or land.

There’s plenty of tutorials on YT on how to move objects along a spline. Do you have a specific issue you’re stuck on or you’re looking for someone to do the whole thing for you?

edit: I think I saw someone fiddle with a skateboard grinding system like this recently. Not sure if it was here or on the forums, though. The idea would be the same.

I’ve tried looking around for lots of tutorials on that subject but what I’m trying to do is pretty specific, I’m feeling if I can’t make it work I might try to get an unpaid blueprint made.

edit: what I mean by specific is how the line works in the demo with the Ai, The player and freight cars being able to use it, I can’t find anything close to almost exactly like it.
