some of the calendar dates: service_id GO403_1246 has dates January 17, 24, 25 has the incorrect year, 2012, or (according to the Barclays events schedule) they are in November
GO403_1246 also has Ronkonoma train 2090 (GO403_122090) which means that train only operates with the Barclays concert service when it should be with the weekday frequency
suggestion: have trains GO403_124106 and GO403_124108's departure times set to 24:13 to 25:02 respectively (ex below)... doing so with changing the hour from 0 to 24 would make the service_id part of the same day but going into the overnight hours, so it can be on the same service_id, GO403_1242
Example:
trip_id,arrival_time,departure_time,stop_id,stop_sequence
GO403_124106, 24:13, 24:13, 12, 1
GO403_124106, 24:19, 24:19, 13, 2
GO403_124106, 24:24, 24:24, 14, 3
GO403_124106, 24:34, 24:34, 15, 4
GO403_124108, 24:41, 24:41, 12, 1
GO403_124108, 24:47, 24:47, 13, 2
GO403_124108, 24:52, 24:52, 14, 3
GO403_124108, 25:02, 25:02, 15, 4
i hope you take this suggestion into consideration
and as mentioned in the other thread: some trips has stop sequences wrong in stop_times.txt such as GO403_123026 and GO403_123031
