Hi there. I have spent many hours toiling over the net looking for a way to make underground coasters and paths. When i see a website with a tutorial for underground coasters, it requires and expansion pack. When i look for underground paths, i found one, but when i try it, all i see is a hole with a path coming out of it, then peeps appearing at the other end. No tunnel. Help?!

oo check this out

I just build the coaster in the ground and thats that all happens for me lol

make a hole, like you would if you were making a hole to put water in it, make a hill for the coaster going into the hole, and then just raise the land back up (i think this is how to do it without the expansion packs.)

I don't think it's possible. If you have the terrain blocks, you could just lower the terrain, build your coaster, raise the terrain around it, then cover the whole thing with the terrain blocks. I think you need the wild expansion to get the terrain blocks. So there really is no point. You might be able to find a CS set for it.

You don't need any expansion to build rollercoasters underground. And the train blocks come with the regular RCT3.
