Raglan station (island) still exists and connected to the running lines if the various www photos are anything to go by.I think that there's no question that with a similar stopping pattern, the EMU would be marginally faster than the DMU because of its greater acceleration, but that's not really the issue. The whole point is that the DMU would be faster running express if it didn't stop at as many stations as the EMU. There's no justification for a separate express EMU just to cater for Bullet passengers and perhaps some from Mt Victoria/Katoomba.
Before dismissing the EMU connection, is there a difference in performance such that with the same stopping pattern, the DMU and EMU will have a different sectional times?
The reason I ask is because the whole anti argument is based on the EMU will take longer. But if the stopping pattern is the same and the performance the same then the only time lost is the change of trains.
The issue with running the DMU to the city is that its then lost for the day. No one is going to fund a 2 car DMU to head west at 10am in the morning. If the locals are happy with a single daily return train and the XPT and future XPT replacement so be it.
However if the locals would accept a transfer service where the timetable is basically equivalent or better than the DMU and at the same time they get a a say 2 return runs during the day, then let it be.
I think it will depend on what the future Dubbo XPT Replacement timetable looks like. If there are two services a day and they stop, Lithgow and all to Dubbo PLUS the Bathurst Bullet, then running through to the city and then likely sent elsewhere during the day is likely.
If the second Bullet through service is implemented, then the earlier service would form the afternoon return service to Bathurst and the later Up Bullet would form the current evening return service, reducing the layover time for each set in Sydney.
I don't see the need for the Dubbo XPT or its replacement stopping between Lithgow and Bathurst if the Bullet provides this service. The intermediate stations wouldn't warrant it
