To do what Maccy is saying: Step 1: Click on the orange brush that you want to make your elevator out of. Press Ctrl-T, and change the "func_detail" to a "func_door". Step 2: On the func_door, change the open direction to "down", change the name to "elevator", and change the Speed to "20" (or something like that) Step 3: Put one of your path_tracks above the elevator, and the next path track where the elevator will stop. Step 4: Open the path_track above the elevator, and set the "Parent" to "elevator". Step 5: On the path_track above the elevator, add two outputs. The first output is "OnPass" - "sspl_train" (or whatever the func_tracktrain is named) - "SetSpeedReal" - 20 (or whatever you set the speed at on the func_door). The second output is "OnPass" - "elevator" - "Open". Step 6: Open the path_track at the end of the elevator and add one output. "OnPass" - "sspl_train (or whatever the func_tracktrain is named) - "SetSpeed" - 0. Someone let me know if I botched this, but I think this is all you have to do. Edit: you probably have to adjust the "lip" on the func_door to make it go all the way down. You'll need a negative number, probably around -64 from the looks of your screenshot.
