That's the way I have interpreted it. If you change platforms at the one station (Flinders St, Museum etc without leaving the station), then I would expect Melton to Stony Point to be a 2 hour Myki tickets. The only way this could come unstuck is if you catch a train from Melton, or Belgrave, or indeed Healesville, and have to change to a Stony Point bus at Frankston....the trip to Frankston would take more than 2 hours, so you will get your 2 hour ticket for the trip, but what happens if you are made to touch off to exit the station, and then touch back on for the bus trip to Stony Point?
Same thing happens in reverse. Travelling to Healesville from Frankston. Does the mere act of touching off at Lilydale (thereby creating a 2 hour ticket), and touching back on on the bus convert that 2 hour ticket to a daily?
Case in point. I recently travelled from Stony Point to Lilydale. I touched on at Stony Point, and the display said "touch on successful". At Frankston I changed from the Sprinter to the spark, without touching on or off (same platform, the sprinter pulled up right behind the spark). At Richmond I transferred to platform 9 via the internal subway, where there are no Myki readers, so again I did not touch on or off. On arrival at Lilydale I touched off (so I thought), but the display said "touch ON successful". What did I do wrong?
It shouldn't be a two hour thing, because in that case it should have just reverted to an all day fare but the card should have remained touched on? If my card had been checked on the Lilydale leg, would I have been in trouble?
