Thread: How can you get your rollercoaster to go up the lift hill on Roller Coaster Tycoon 3?

I enjoy playing roller coaster tycoon 3, but every time i go to make a coaster and i try to get it to go uphill the rollercoaster either rolls back or stops at the bottom and just won't move?
Please help!

You have to remember to put a chain on the the lift hill, you cannot just make a hill you have to have a chain to lift it up.
