They are due to end with the timetable change next Sunday, so this Monday-Friday will be the last 5 days of their operation on this route. Currently there is only one morning diagram, the 07:44 MDE-CHX. In the afternoon and evening two sets are allocated, one does the 15:25, 19:25 and 23:25 VIC-AFK, with return journeys on the 17:27 and 21:26, the other does the 16:59 CHX-AFK, returning to Victoria on the 18:55. Both are 4-car Monday and Friday and 6-car midweek.
I have been wondering if 465908 will get allocated to the route this week, as it hasn't yet done it in its NSE livery. If it doesn't do this week, it probably never will, unless a farewell tour involves it that covers the route.
