Seems this thread has gone off track ( pardon the pun )
Thought it was about "Retiring of the 2000 class Railcars"
Regarding going off track, as from today so are the 2000 class Jumbos.
Is there some ill-founded, financially destitute rail system or scheme we can wish them on?
I have suggested elsewhere that the elephants grave yard is the place for them.
For all that they were a step up from the Red Hens, probably an even greater step than that between the Red Hens and the Brills.
The Red Hens matched Adelaides service needs, the 2000s did not. Over powered and over weigth as two cars, underpowered as three cars.
IMHO the plusses for the 2000s were the air con, powered doors, PA, Air-ride suspension AND the raised cab.
Down side, the mass, repeat, the mass, the small windows, the claustrophobic interior of the power car, the generator in what could be passenger space.
At the time Adelaide would have been better served by building loco hauled cars for push pull service for use on the peak hour trains only. If you look at the specification for the 2000 class that's what STA were trying to achieve. The push/pull system works well in the USA. With the standard cars you need a few driving cab (only) cars complete with underfloor generator for the train air con; controls have to match the locos.
Thankfully they learned some lessons and for all the objections the 3000s match the systems needs. I only hope the new electrics are as effective.
