As mentioned before, the commuter double decker trains in the Netherlands DDAR (built 1991-1996) have been refurbished to DDZ. Within now and a few months, half of the trains will be extended from 4 to 6 carriages.

Internal doors

One thing I notice in the photos is additional doors between the vestibules and each deck, do any Syndeysiders wish they had those same doors?

In Europe, this is common on intercity and long distance regional trains.
Seating areas are separated of the vestibules by doors.

But on my trips to Syndey, I don't recall such doors even on interurban sets. The big thing about those Sydney trains is this; When you travel on either deck, you are on a separate level from where one boards or alights, almost like being in a separate room from it. Adding doors to those decks would add to that separation.

Would that be good or bad?

(post-GDR) German regional double decker coaches do not have separating doors between both decks and the vestibule. Some do also have the doors on the lower deck. Don't know about the coaches buildt by the GDR Reichsbahn, though.

In France suburban trains (RER and Transilien) don't have a separation but interurban (TGV) and regional (TER) have a separation.
Usually the lobby is the part of the train where you can use your phone without annoying the other passengers.

These separation doors are mainly a relic from the past, from the time the transfer tunnels between the cars (or is there an other English word for that?) were very noisy. By using 2 doors you could somewhat shield the passengers from those noises. Added bonus of course is that they also dampen the platform noise during stops.

I've thought of an articulated double decker railcar with three vestibules, the third between a pair of artuclations, and its length would be the minimum needed to accomodate doors.

For the idea, kind of like putting a vestibule in what is now the motorcar of a Stadler GTW?
That concept, but with slightly longer cars, is also used by Bombardier with the Omneo.

Hi, just wondering is it possible for 1000mm gauge double deck trains.

The trains in malaysia even the newly launched electric ones are only 6 carriages long and some of us would love to see double deck trains in the future. But is it technical posisble or adviseable as the 1000mm gauge may make the train unstable at high speed. Malaysian ew double tracked lines in the Malaysian peninsular west coast is relative straight.

The only reference of a narrow gauge train is in japan like the Super Odiroko which is on 1067mm gauge.

Another one, best example:

JR East 215 series (1992)

More important then the track gauge is the height and width of the loading gauge (the height and width of the carbodies). For a metre-gauge railway it's likely to small to make double deckers feasible.

Indeed. There are broad gauge railways where the loading gauge doesn't allow for double deckers, but on the other hand there are narrow gauge railways where double deckers are possible. See the examples from Japan.

The problem with narrow gauge is that running at higher speeds is not problem unless you really keep the track geometry perfect. But in Japan they probably won't have a problem with that...

Is there anything in the pipeline among high-speed double deckers? It seems the TGV duplex is the only one out there currently since the japanese withdrew the E4 in the last 2-3 years.
Maybe a new shinkansen with double-deck? AGV double-decker?

No more double deck shinkansen trainsets will be built as they no longer fit the current operating philosophy or customer needs. As far as in Europe, I know of no new designs- Alstom is still producing their Duplex model. Not really "very high speed" (230km/h), but Bombardier's (delayed) Twindexx Express model for SBB, slated as the replacement of the IC2000 trains, seems to be the newest of the genre, prototype cars have been seen being hauled around recently on the rails.

The current Dasye/EuroDuplex will be very difficult to replace, because they go against all current trends:
  1. Power cars instead of distributed traction. The latter is nearly impossible to do with a 17 tonne axle load limit and Jacobs bogies (an Alstom centre-piece) => Use 'regular' bogies
  2. The capacity difference between a Duplex (508 seats) and an AGV (NTV: 460 seats) isn't that big anymore (compared to 377 seats on a TGV POS)
  3. There is no 760mm platform variant
  4. More passengers via fewer doors => longer dwelling times
  5. Lower ceiling heights => Cramped feeling for the passengers (a Duplex is just 4,32m high, against 4,67m for a Dutch VIRM set for instance)

The E4 suffers from 3. and 4., but also from it's limited 240 km/h top speed and it's 6 abreast seating in regular class. If needed I have no doubt they would reintroduce double-deckers in a hart beat, of course incorporating the lessons learned from the previous generations.

TGV Duplex: 320 km/h

Shinkansen double deck:
100 series, two floors in 2 or 4 cars of some series (1986/2012) 66 sets
E1 series (1994/2012) 6 sets
E4 series (1997/2016) 26 sets

Here's a thought, how about a Double decker trains vlog? The idea is for the host(s) of the vlog to film anywhere (possibly by request) on any railway network, other than the Sydney and NSW trainlink network, where double decker trains are a considerable portion of the fleet, such as the Paris RER.

And here's a thought. An individual double decker train can carry something like 50% more people (under normal loading conditions) than an equivalent single decker. How far does it need to go without stopping to carry (almost) 50% more people on each service?

There are metre-gauge double deckers in Vietnam. There should be a few photos on Flickr. I was surprised to see metre-gauge double deck trains too the first time when I saw them in my friend's photos when he visited Hanoi.
