Here’s an interesting issue with Myki which has always been around to an extent, but which has got worse with the switch to exact two-hour fares.
This implementation is in contrast to the fare rules, which say your fare lasts for as long as the trip, as long as you started it (touched-on) before the expiry date.
Here’s an example: Board a 903 bus at Mordialloc (zone 2) at and touch-on at 9am. Ride to Northland (which is in the zone 1/2 overlap) and touch and alight at 11:10am.
What should happen is you get charged a 2-hour zone 2 fare.
But because it’s more than 2-hours since you touched-on, the touch as you alight will be treated as another touch-on.
You’ll end up paying a default fare (zone 1+2 because that bus route eventually terminates in zone 1) for the original touch.
Plus if you don’t notice as you exit the bus that it’s touched you back on again, you’ll pay another zone 1 fare on top of that, because it will have assumed you travelled from Northland (zone 1/2 overlap) to Altona (zone 1), $3.58.
So a total of $9.64 for what should be a $2.48 fare.
The silver lining is it’s not a very common scenario.
But it can happen, on some bus routes (such as the very long Smartbus routes), and on trains as well, where cross-town trips may take over two hours.
For trains, as you exit the station and touch, as long as you notice it’s touched you back on and charged a default two-zone fare, perhaps the easiest thing to do would be to wait 30 seconds, then touch-off again — invoking the “Change of mind” feature. The 30 seconds is so the reader doesn’t think you accidentally touched twice. You’re still charged the initial two zone fare, but that’s okay, because any conceivable trip of more than two hours would be a two zone fare — except perhaps if there was a long delay en route.
This isn’t possible for buses, because they have no “Change of mind feature”, and even if they did you might still be overcharged.
It’s also a bit tricky if an epic train trip ended at fare gates, perhaps at the end of the line at Frankston for example. Staff on the gates should be able to figure it out for you.
The official solution
If a customer using myki money does not touch off the myki within 2 hours after it was touched on, a default fare may be charged when the myki is next touched to a myki reader. Such a touch will also be treated as a touch on
To prevent this happening, a customer may touch off the myki prior to the end of a journey, but must then touch the myki on —
(a) in the case of a journey on a tram or a bus, immediately after the myki was touched off; or
(b) in the case of a journey on a train, before resuming the journey.
In other words, you should touch-on as you board the bus. Then along the way, you should touch-off, then touch-on again. And finally at the end of your epic trip, touch-off again.
Presumably this advice is intended for staff to pass onto affected passengers — few Myki users would be aware of this, nor should they be expected to read the manual (but it’s good the manual exists, so that interested people can get this info).
If they’d thought about how the software might be used in the real world, then (at least on buses) they should be able to figure out that as you exit the bus after a long trip, you didn’t really magically travel to the end of the route (before the bus itself got there) and then board it again.
It’s a reminder that the implementation of Myki leaves a lot to be desired.
PS. For longer V/Line trips, the fare extends to 3 hours for 6 or more zones, and to 4 hours for 12 or more zones. See: PTV: Myki on V/Line.
