(Metro) Can we increase the mainline / suburban rolling stock to 130/140?
:Suburban rolling stock
my reason why I am raising topic, this is because the suburban top speed is 110km, while other parts of the suburban network can reach 160km or 130/40.
but the suburban trains are restricted to 110, there isnt anything blocking in the way to reach top speed and im confused why are we not maxing the top speed on the Siemens (130) , HCMT (140), extrap 2.0 (130)
I do know that extrap 100 will be restricted to 100-110 because of their horrible suspension, but are build to handle 140km to keep in mind. is the reason is because of the break/signal is the problem? or the government haven’t spend enough to reach that top speed?
: Mainline
for the mainline, Im raising this topic aswell because for example pakenham line, from Beaconsfield - Pakenham the top speed is 100. the geography shows that the line is straight with no curve that the line can handle 160 - 200km. same line example I can give dandy to Oakliegh the top speed is 80, but same agian it can reach better speed 100-110km. is there a main reason we cannot get a better speed on the other lines (i am talking about express trains and big gaps between the stations aswell not local trains stopping all stations)
