They COULD be compatable if Cityrail really wanted them to be - the AC
traction system could be made to adapt to the other power cars.

I expect that the AC motored trains would be more compatable with the
DC Chopper sets than the DC choppers are with the camshaft units, and
Intercity mix choppers and camshaft units all the time.

Any train with an electronic traction system can easily have it's
characteristics altered (with in the limits imposed by things like max
motor current and speed), it's just a set of tunable parameters to the
little computer that drives the traction components.


The ill fated AC motored G7 Outer Tangara spend it's entire working life
coupling with DC motored Tangara sets.

Will the new OSC's be MU compatable with the M sets ? (Which should have
been MU compatable with the T sets, but....)

Anything can be made compatible if there is a solid enough business
case for it, to demonstrate the benefits outweigh the costs..... but
it's hard to see what the business case could be in this instance.

Its a lot more complex than that.

If you asking if there is a replacement for the V Set, the answer is no.

OSCA are wide gauge. Won't go west of Springwood.

Passenger alarm buttons. They set off an alarm (and may be stop the
train as well) when pressed.
I recall that they locked in as well, a guards key was required to reset
it.
I was on a train at Central once that was delayed 30-40 minutes as some
one had gone through and pressed ALL the alarm buttons in. After reseting
a couple the driver gave up and called a 'quipy who then proceeded to
divide the train to isolate the fault - only after another 15-20 minutes
releasing that some low-life had walked the 8 car set pushing EVERY alarm
call button.
Not long after those covers started appearing over the alarm buttons.

Incorrect. They are standard gauge.

G'day All

There are three passenger car width profiles in NSW. The approximate
dimensions (in old units) are:

Wide electric stock = 10'6". I believe this was decided by Dr Bradfield
as he wanted the world's widest cars. It was to be applied system wide
(never achieved). Applies to old single deck electric cars. Limited to
suburban area (Emu Plains, Cowan etc)
SAR and CR used this width profile for all vehicles.

Medium electric stock = 10'00". All double deck suburban and outer
suburban cars including new ones. Can go to Newcastle, Kiama, Springwood.

Narrow stock = 9' 9". Applies to all non-electric stock and V sets.
Exception: wheat and coal wagons are 10'0" at widest point.

Recent modifications to platforms means that wide cars must now run at
reduced speed through them. This means the end of 1920's plans to have
USA loading gauge in NSW.

Reminds me of the time when heritage electric set W3 was first trialed
through Olympic Park platforms. It wasn't the single deck power cars
that came close to the platform edges, but the two Tulloch double deck
trailer cars ... which at the time were identical to the numberous
Tulloch trailers in regular service through trhe platforms!

"Outer Suburban" means that area between Emu Plains and Springwood currently
serviced by G/T's. Beyond that is called "Intercity" (yes, not a true use of
the term)

OSCA is wider than M Bug, wont get thru Linden Railway Station, the road
bridge at Lawson, and a few other locations on the line.

I dont know if it is called "Medium" or "Wide", but only "narrow" stock goes
west of Springwood, which it OSCA aint!
