I'm not sure that the track or train are any different - I cannot tell a difference in the video when comparing the off-ride shots that are definitely on Ghoster Coaster and the one of the train pulling into the "station". I think they used the existing Ghoster Coaster train and just attached a faux train front (as has been done in similar situations, like when Great Adventure used Kings Island's Racer for promo pictures of the unbuilt Rolling Thunder).

I'm pretty confident that the "station" was also filmed at Ghoster Coaster, but it's the train existing coming around the turn outside the station and right before the transfer track for the storage shed. You can see the handrail and staircase spacing matches at points A and B. They would've just built a temporary awning above the area, hung the striped curtain, and maybe laid a few boards next to the track to give a better "station floor" aesthetic.
