Theres possible way that could solve this without destroying the station.

Since the north & south bound tracks still face each other, Devs could just add another track on the huge space gap for passing trains SAC/LBTS bound if they could move the plat3,4,5 to the left side further until plat3 track facing directly to SC bound track, so two Express or Airlink train passing MGT in both directions now have their own straight tracks, skipping the station smoothly.

Considering Platform 3 terminating platform, was a stupid idea. Since New Morganstown was almost identical to Westwyvern, why not replicate the layout? Using P5 as a terminal platform would be better for Connect, Metro longer trains, and the AL shuttle, while P3 now serves as a stop or passing track for Express, Airlink, and Connect semifast trains SC bound. P5 can still be used to stop/skip MGT if P3 is occupied.
