I just contacted MBTA and Keolis with permission about adding their MPI HSP46 with Rotem Bi-levels as a paid DLC for Train Simulator 2021 and the permission was granted. The huge question is, can someone make the MBTA MPI HSP46 with Hyundai Rotem Bi-Levels? I really want this DLC very badly. And I'm not good at making these content. I wish the developers can make these MBTA Bi-levels. I have autism and I love trains and love these Rotem bi-levels.
