Please download the fallowing GRF Pack, because the PGS Stations were renamed: ottdc_grfpack_old_pgs.zip.

The settings are for new nightlies with GRF Pack 4 upwards, if you use older releases (i.e. 0.5.1), you have to remove the paths from the file list.

from beginning until SB-Game #15 and Werkloze Desyncs, Inc. on MS (DBSet)
