They use to do small possessions here and there as required on several lines during each weekend.
People complained about getting off and on buses on two or three occasions
So they changed to it one big possession.
Really depends what needs replacing/maintaining .... it's worked out up to 5 years ie proper southern endet management programme.
Some of the possessions are to unravel some of the old bottlenecks ..... that programme has several years to run
Out your way the resulting possessions are a consequence of the particular line configuration you have
It is very complex ... electrical switching in a particular section often determines where the ends of the possessions are
People **&$^#% whatever you do.
Some of the complaints are just pathethic (and hilarious)
So you can either call the glsouthern end half full or half empty
Get in the car and drive to the station that has a train service or just complain to the infoline on 131500.
If you have a look at the other capital cities, you will find they have a mickey mouse operation compared to sydney .... we have 300 stations .... 1700km electricified line ... 2900 services a day.
If you don't maintain it .... accidents will eventually happen
As for lateness, stop a lot of the vandalism and trespsouthern ending by the trailer trash on the network, and you will reduce the lateness by half
;D ;D ;D ;D
