The presenter in the video said that he could not indicate exactly when
it would open, though perhaps somebody here is a little more in the know
on a tentative opening day?
As I said previously, they're aiming for March, subject to successfully
completing the various emergency and evacuation drills.
The irony of course is that its probably not really needed now if WFH continues
to any great extent beyond covid.
One question no one has answered - does it count as part of the underground?
It's been answered many times: No, and not LO either. Despite the name,
it's regarded as a network in its own right, at the same level as LU, LO
and the DLR. At stations like Stratford, you will see roundels for each of
them.
More like RER, IMHO.
Yes, it's similar to the RER.
Reminds me of a German S-Bahn.
No, they're main line trains; S-Bahn trains are more lightly constructed,
and often third rail.
S-Bahn is more of a branding exercise than a meaningful technical
definition. > In most places, S-Bahn branding is applied to urban and
suburban rail services in a city or metropolitan area that are, in
technical terms, simply normal mainline railway trains, operating on
shared infrastructure with the mainline network.
There is PATH in New York City and PATCO in Philadelphia, which are
S-Bahns as it crosses certain borders, yet stay relatively close to
their centres, such as what we might see in Germany as well as here.
In Philadelphia, I would regard the SEPTA heavy rail as more akin to an
S-Bahn than the PATCO, which is essentailly a fully segregated metro.
SEPTA Regional Rail is most definitely commuter, while the Norristown
Line is still an Interurban.
It is a collection of formerly disconnected suburban lines (the PRR and
Reading lines) with through running across the networks enabled by a
city centre tunnel. That's pretty much exactly how the RER in Paris
was created, and similar to both Crossrail and Thameslink.
Post by h***@yahoo.co.ukPhiladelphia has its own subway system, the Broad Street Line and the
Market-Frankford Line, in addition to PATCO.
Lots of cities have metro systems comprising of lines of different
technology and character where throguh-running is not possible, but are
still in essence metros. The DLR in London, for example, is in all of
its characteristics a metro system, separate from the tube and
subsurface lines. Paris has both rubber tyred and steel wheel lines,
and a few driverless lines, while other lines are manually driven. New
York has the IRT lines that can not accommodate rolling stock from the
BMT and IND lines. Just because a line uses a different system,
doesn't mean it might not also provide a metro type service.
Post by h***@yahoo.co.ukPost by BobYou need to be careful with the term commuter rail in a North American
context, as that often is used for systems that are peak hours one way
only (so trains operate from suburbs to the city in the morning and
from the city to the suburs in the evening, with no other service).
Huh?
Metro-North, SEPTA Regional Rail, New Jersey Transit, MBTA Commuter
Rail, the Long Island Rail Road and even CT Rail's Shore Line East run
in both directions off-peak as well as in peak. In fact, some of these
services run almost around the clock, if not around the clock.
There is also such a thing as reverse commuting.
Yes, there were some lines that limited their services to peak, such as
CT Rail Shore Line East, and NJT/Metro-North's Pascack Valley Line, but
they've pretty much gone full time.
MARC does not run weekend service into West Virginia, IIRC.
While the characteristic of peak hours only, one way tidal flow is not
a universal characteristic, it is a feature of several systems, and in
some discussion of the systems in operation, some people do make the
distinction between commuter rail, with this peculiar characteristic,
and regional or suburban rail, to imply a more consistent service
pattern. I just thought it was worth mentioning this in order to avoid
the potential for misunderstanding how terms are used. For example,
from https://en.wikipedia.org/wiki/Commuter_rail_in_North_America
"Many, but not all, newer commuter railways offer service during peak
times only, with trains into the central business district during
morning rush hour and returning to the outer areas during the evening
rush hour."
Post by h***@yahoo.co.ukPost by BobIn terms of what is and is not an S-Bahn, there is no clear definition
as different cities use the term for different things, from Berlin
where it is practically a metro, to somewhere like Dresden where it is
little more than branding applied to conventional suburban services.
Post by h***@yahoo.co.ukIn Berlin and Hamburg
Post by Bobthey use 3rd rail electrification that is otherwise non-standard, and
largely on dedicated lines, but the actual technical standards to which
the trains are built are still UIC compliant. In that sense Overground
I don't know what Overground is, to be honest. It seems to be a cross
between S-Bahn and RER service, combined with seating from South
Africa's Metrorail services.
What distinction are you drawing between S-Bahn and RER? Asside from
one being in Paris, and the others being in German speaking countries,
they are functionally interchangable, with for example, the Munich
S-Bahn being basically the same in concept as the RER.
Post by h***@yahoo.co.ukPost by Boband Crossrail are both S-Bahn in concept, as is the Paris RER.
I consider Crossrail, Thameslink and Moscow's MTsK as well as the new
MTsD to be closer to RER.
That begs the question of what distinction you are drawing between
S-Bahn and RER.
S-Bahn I normally associate with third-rail, metro-type service,
whereas RER is more OHLE, with higher speeds.
There are something like 16 S-Bahn branded networks operating in
Germany (depending on whether you count the cross-border Basel and
Satzburg routes). Only two of them have this characteristic (Berlin
and Hamburg), the remainder are conventional mainline rail, standard
(for Germany) OHLE powered, and largely indistinguishable from RER type
services.
Post by h***@yahoo.co.ukHaving said that, I realise that the Vienna S-Bahn is likely closer to RER.
Along with Bremen, Rostock, Hannover, Magdeburg, Dresden, Köln,
Rhein-Ruhr, Rhein-Main, Rhien-Neckar, Nürnberg, Stuttgart, München,
Basel and Satlzburg, plus a number of S-Bahn branded systems in CH and
At.
