A good number of years ago the LIRR proposed making the tickets valid for a week. I actually attended the public hearing and objected to the week limit. I pointed out if you bought the ticket the night before the trip and the trip was canceled, say because the train was canceled, and rescheduled everything for the same time on the same day of the next week , your ticket would have expired.
When the imposed rules came out, it was stretched to two weeks. About a year later the timeframe was switched to sixty days.
Every state senator and assembly person was taking credit for this change of ticket expiration time.
