Probably something most of you have already taken care of, but in case anyone hasn't gotten around to it, this should help. A couple problems we've noticed with Metra's GTFS that have gone awhile without being fixed:
Hope that helps someone.
stop_times.txt, add:
NCS_NC120_V1, 19:33:00, 19:33:00, LIBERTYVIL, 10, 0, 0
NCS_NC120_V1, 19:43:00, 19:43:00, LAKEFRST, 12, 0, 0
These two lines will add stops for NCS #120 to Libertyville & Lake Forest on the MD-N line. NCS train #120 makes two stops on that line, but Metra generally doesn't include them in their gtfs data.
