I'm looking to book a trip from Sydney to Orange on NSW's XPT train system. Up until the end of March it's $37 for the trip, after which it's $53 for the same trip.
Does anyone know if NSW TrainLink uses a system where ticket prices come down closer to the day, an availability dependent system (like airlines) or if there's a high/low season cut-off?
I'm trying to determine whether I'd be better off booking later (as looks to be the case), or immediately (if it's either of the latter two systems).
