And when Comeng started delivering DD power cars, the manual door
trailers were converted to POD compatible configuration.

When the original 120 Tulloch DD trailers entered service from 1964
the first 40 replaced the single deck trailers in the POD, 120v
control Sputnik “S”, later “W” sets. The SD Sputnik trailers
lost their PODs and were rewired for 36v control and lighting and
cascaded into other, non POD single deck car sets. After the “S”
sets were reequipped with the DD trailers the following 80 deliveries
from Tulloch were non POD, 36v cars compatible the older rolling
stock.
These cars were the replacements for the old, three doors per side
wooden trailers that had been rebuilt from steam suburban stock.

But remember in those days the air conditioning for the passengers
was the fact that the doors were only closed if it was raining 
and the rain was blowing inside. Otherwise the doors stayed open. I
don't think the first double deckers had power operated doors, 
and I am fairly certain that they were only marshalled in sets without
this feature.

Hi Tony,

The proposed use of single deck trains went beyond the Bankstown loop.
These trains were also considered suitable for all stations 
to Hurstville, to Liverpool, to Parramatta to Epping and to Lindfield.

The plan was for double deck trains to operate with only limited stops
to Hurstville, Liverpool, Parramatta, Epping and Lindfield 
and all stops beyond.

The difficulty arose with passengers from city stations boarding the
first train to arrive for a journey only to Redfern or North 
Sydney and taking up the seating intended for passengers travelling
longer distances. The long distance commuters would then wait 
and wait for a train with spare seats and add to the overload on
platforms at Wynyard and Town Hall.

We probably needed strict regimentation of passengers at city stations
with “pushers” similar to those in Japan. Passengers standing 
near train doorways keeping the doors from fully closing with their
foot didn’t help either.

Hi Noel. The version of events that I gave is what happened and is
supported by Dornan and Henderson in their account of NSW 
electric railways, written close to the events in the 1970s. The
deckers came about because they couldn't for various reasons get 
more capacity out of the system so they felt that they would try
instead get a bit more out of the trains while retaining the 8 car 
length as you say.

It would be difficult to roster the solution you suggest as mostly
they're the same lines serving both inner and outer areas. About 
the only short-distance line you could preserve for single deckers in
those days might be the Bankstown/Inner West loop.
