M I refuse to believe that its impossible to have a bit more traction motor , may be impossible with existing examples but not impossible to make .
To have a true weight comparison you'd have to combine the weight of the inverters with the AC motors and then they don't look so light .
Yes Rail Corp certainly do , 90 classes to Delec and 90 classes to Erraring . Go figure ...
Maybe you're forgetting that SSFL splices back into the ARTC network south of Macarthur .
I doubt two 93s can pull what three NRs can , be interesting to see 93+93+3900T on the 1:40s down south . Tell me how fast again the three 92s went up Cowan Bank with 4500T or 1500 ea . Be really painfull with 1950 each .
We've had plenty of practise but WE didn't design the system .
Now lets see - don't recall SCT running too many eastern state services with in line fueling operating , in NSW anyway .
I also don't know for sure but it sounds like the Gs had a purely gravity feed system from the fuel tanker and it may be the same with the GT46Cs , not sure there . Its seems a minor issue with gravity feeding and no pump is how to detect leaks . NSW doesn't like leaks .
I believe NRs and C44ACis use a pressurised fuel tank system so I guess gravity feeding doesn't work so well .
I believe NSW has a problem with many thousands of litres of diesel fuel potentially being dumped along its rail corridors . This is rumored to have happened out in the wide open spaces where no one else was around to see , in another state .
Frequency of fuel system failures , I can recall BM4 twice visiting Pt Waratah because of leaks etc with these ACs and at least once pinching an NR to get the train to Melbourne with a dead 93 . Two people got a taxi ride from Chullora to Broadmeadow to work that one to Sydney , guess who one of them was .
Have spent time in our terminal fighting the tanktainer to prime enough fuel into the 93s to make Melbourne , another BM4 layover in Sydney because it missed the afternoon peak . We should virtually never see 93s at our fuel point and they do look rather stupid being refuelled with the tank tainer still attached .
I can recall MB4 being in the terminal several times in recent months , no attach/detach - justs 93s in for a drink .
Do I have to spell out what this does to through trains on time running and reliability ? Would it be any better for an SP5 or Sprinter service to run out of fuel in the middle of nowhere ?
By all means , try them out across the west because it'll be too far away for us be concerned with .
People are initially keen to drive these things and then universally don't want to know any more , curious .
