Hydraulic Launch?

[Brtnboarder495]

I thought TTD used a catapult system but it uses a hydraulic launch system according to RCDB and other sources. What is a hydraulic launch and how does it work exactly?

do u know wat hydraulics are? if you dont go here http://science.howstuffworks.com/hydraulic.htm

wat it will be is a hydraulic motor pulling the cable to create a catapult which is used on TTD

i hope that is write if not currect me

They call it a catapult somply because they pull the cable on direction to make the train go in the other direction. This is accomplished using hydraulics.
