I've been meaning to look into this myself. You select a Ground Unit, set the Category to "Train", pick a spot on the black train tracks on the map, which can be hard to spot until you're zoomed in pretty far. There are multiple wagons to be added to the train in the right-most tab in the Vehicle Group for the Train. You can add them in order much like Waypoints, I think. I am just trying this now.

Oh, you probably mean this video, and yes, it's Grinelli's F22 which isn't out yet as far as I know:

It was an ID10T problem, I was looking at the wrong downloads and was using the non-SFM version. Only issues I ran into so far: E2D's engines don't stop animating or emitting sounds when you shut them down. They stop giving the aircraft propulsion, though, so that's working. E2D's landing gear doesn't appear to work. It raises and lowers, but you land on your belly and crash instead of landing on your lovely landing gear wheels... Very cool, thanks for making me look again! I'm a dummy. Have a link to the video? All of these mods use a preexisting cockpit, usually the F15 or SU-27 (Flaming Cliffs 3, all non-clickable). I think you can also set it up to use a clickable cockpit, but I haven't seen it yet.

I think I followed the instructions correctly, and I can't fly these mods. I'm running 2.5.6.60966

I can usually go to Edit Controls, then the Rescan button, once to "disable", and a second press to "Enable" IR Tracking again.

Compare graphics and gfx driver settings between clear and bugged environments?
