Perhaps not the biggest issue around, but it may be worth noting that there's a missed opportunity with the new timetables, now that there's a 10 minute frequency from Dandenong as well as on the Frankston line.
During weekday mornings, after the am peak until lunchtime, the expresses from the Pakenham/Cranbourne lines heading to the loop arrive at Richmond at exactly the same time as the trains from Frankston heading to Flinders Street. If things are all on time, this makes a transfer impossible. However, if the express arrived a couple of minutes later, then Frankston line passengers would have a more reliable connection to a loop train (instead of waiting variable periods for a Box Hill group train).
This wouldn't prejudice the connection at Caulfield for passengers from Pakenham/Cranbourne trains heading to a MATH station. In fact, as it would mean a 4 minute wait instead of 6 for the stopping train, it might even be regarded as better,
In theory, passengers from the Frankston train can transfer to the expresses at Caulfield, but there's a long ramp there (the steps at Richmond are quicker for many people), and in addition, changing at Richmond provides the back-up of a Box Hill group train if there's a problem with the Pakenham/Cranbourne line train. And, of course, this option isn't available for passengers from MATH stations.
