New York Computerizes its Subway System
Iphtashu Fitz writes "New York City's Metropolitan Transit Authority launched it's first fully computer controlled subway line this month. The `L' Line of the MTA that connects the southern part of Manhattan with Brooklyn was picked for this pilot program because of its relatively short length and the fact that it doesn't share tracks with any other lines. Trains on this line no longer have conductors on board, and only a single driver in the front to monitor all the systems.
What's the big deal, you may ask? After all, cities like San Francisco and Paris already have computerized subway lines. Well, having recently celebrated its 100th anniversary the MTA is one of the oldest subway systems in the United States, and one of the largest in the world. If all goes well, the MTA will continue to expand automated service to the rest of the subway system over the next 20 years. But just how safe and secure will these new automated lines be? The radio links that provide data communication between the trains and the control center are encrypted, but how long until a hacker manages to crack it?"
actually, the bombs were dropped during the II World War, that is 1945. it will mark the 60th anniversarie.
Without a conductor, who's going to yell at everyone to stop holding the doors? How does this work in other automated systems, like Paris's Météor?
Trust me, you don't hold the doors -- you can't, they're too strong. Or maybe you can, but I've yet to see someone try (even though that's a local sport on other, non-automated lines -- it's not like nobody ever holds doors in Paris).
They make some kind of "sound of inevitability", loud and somewhat fast. Then, there's the fact that there are two set of doors per opening (one for the platform, one for the train itself), twice as much to hold when compared to the older lines.
Finally, there's decent traffic on the line, you don't have to wait much if you miss a train (except after 10pm, when you need to wait five minutes or so).
So, as much as it occured even to me to hold the doors for a nearby friend on other lines (nearby meaning really nearby, not at the top of the stairs far over there), it never occured on line 14 (the automated line).
Non-New Yorkers may be excused for not getting our backward terminology for train staff.
The 'Conductor,' who in the rest of the worl drives the trains, sits in the center of NYC subway trains and opens and closes the doors, and announces stops (until the recorded voices in recent trains, that is).
The guy driving the train up front, and looking for kids and other garbage on the tracks, is called the 'motorman.' You see, he's the guy that turns the motor on and off. Or something.
Anyhow, they're planning to eliminate the conductor, but keep the motorman- so there will still be someone up front watching for imminent collisions. When they're not asleep, that is.

The Skytrain in Vancouver BC is completely automated, and it works well.
The doors have "pinch" sensors, and while people can use them to get the door to re-open, it only re-opens three times until the system flags a central operator. Usually people start yelling after the second time.
In emergencies, there's a panic strip and a comm system, and cameras.
There are control panels, but they're only used when something bizarre has happened on the track and manual routing is needed.
I don't know about Paris' underground system, but some new systems install double doors, doors on the platform that match the train doors. It isn't possible to hold each one open at the same time easily. New sections of the london underground have it. it also stops suicides as the inner doors only open when a train is stopped.
Not that I've ever seen a conductor on the london underground, either on the train or on the platform. Just some monitors for the driver to see, and a populace who can behave to some extent.
Here in Vancouver, we occasionally have an issue on our automated rapid transit trains with people holding the doors. Luckily, in the absense of a conductor to yell at the fool holding everybody up, the other train passengers take on this role. The doors will try to close, and if obstructed, will re-open for about 2 seconds. If you're still in the way a second time, people start to voice their annoyance that you're making them late for work.

Altering time, one time at a time.
Nuremberg will introduce a completely driverless subway next year. Good article with lots of pictures. See (partially English) PDF
I for one welcome New York to 20'th century technology while we live in the 21'st century.
Do not confuse CONDUCTOR and TRAIN OPERATOR (read on) What they're not doing: - They're not phasing out the train operators. It's no going to happen.
In Paris line 14 has no driver, no conductor, no train operator, nobody. You can even sit on the first wagon and watch the view! So there is no theoretical problem from removing drivers, of course I suppose the line is still monitored by humans.
and for the fact that many homeless tend to like to live in tunnels.
That's irrelevent, it's not the drivers job to keep homelesses out anyway.
Actually, in the rest of the world the Engineer is who drives the train. The conductor rides the train and checks tickets and whatnot.

Unless it's a Walt Disney World Monorail, then the driver's title is Pilot (it's not on the ground
Yes, I hate being called a Conductor.
Does the name Pavlov ring a bell?
We have a number of automated lines. THe Docklands Light Railway is fully automated and runs really well. At least 3 of the lines on the Tube are computer controlled too with the drivers there to monitor the doors.
However the automation ahd led to some interesting and unforseen difficulties. The automated systems speed up and slow down at the same points in the track it is putting extra stresses on certain sections of track and sleepers which leads to degraded track safety.
Working for the (other) man
Actually, in the rest of the (non-US) world, it's the Engineer who designs the train. The driver drives the train.
