Yes, I have played X3 before, so I am well aware of what Jump Drive does.

Travel Drive comes with the Lucike's script collection, hence you don't see it in your game. Very hard to find info about it.
BTW, the Lucike's collection adds jump beacons, which AFAIK, allow you to jump right to them, instead of gates.

They are like satellites, have to buy then first from the JB factory.
