Subways Run by Computers Start on L Line This Summer

January 14, 2005
 By SEWELL CHAN





After delaying the project for months because of safety
concerns, the Metropolitan Transportation Authority will
start operating its first computer-run subways in July on
the L line, which connects Brooklyn and Manhattan,
officials said yesterday.

The debut of computerized train operations, which would
replace a signaling system largely unchanged since the
birth of the subway network in 1904, was first scheduled
for December. Officials insisted yesterday that any
outstanding concerns about safety would be resolved by the
start of the summer.

New details about the project, a longtime goal of engineers
and transit planners, emerged at a City Council hearing
that became the scene of vigorous debate over the merits
and safety of the new system.

The most divisive element of the $288 million project is
the elimination of the jobs of conductors, who open doors
and make announcements, and the use of only one worker, the
engineer, on each computer-run train.

Limited "one-person" train operation began in 1996 and is
now used on seven lines, but only two of them - the
Franklin Avenue shuttle in Brooklyn and the Rockaway Park
shuttle in Queens - are operated without conductors at all
times.

Roger Toussaint, president of Local 100 of the Transport
Workers Union of America, said the authority was trying to
eliminate conductors' jobs to conceal the high cost of the
new technology.

"One factor that seems to be driving this rush is the
desire to show immediate financial benefits to justify the
large expenditures that have been made," he said. "Since
there will be no short-term benefits in revenues, New York
City Transit has married to the new technology a plan to
take conductors off the trains. This plan flunks the basic
test of common sense."

Members of the Council's Transportation Committee, some of
whom referred to the project as robo-train, were equally
critical.

"Having computers drive our trains is a huge leap forward,
and we must look before we leap," said Councilman John C.
Liu, a Queens Democrat who leads the panel. Councilman
Lewis A. Fidler, a Brooklyn Democrat whose district
includes part of the L line, said the new system would make
it harder to evacuate passengers after track fires or other
emergencies.

However, the project received a boost from a key
rider-advocacy group. "While safety concerns must be
addressed, we cannot be afraid of proven technologies that
make the system operate more efficiently," said Beverly L.
Dolinsky, executive director of the Permanent Citizens
Advisory Committee to the transportation authority. The
group first advocated signal improvements and conductorless
trains in 1982, she said.

The new system, known as communication-based train control,
has been long in coming. From 1992 to 1997, New York City
Transit, which operates the subways, ran a demonstration
project on the middle track of the F line in Brooklyn, said
Frederick E. Smith, a deputy chief engineer in the agency's
department of capital program management.

By late 1997, officials had chosen the 24-station L line to
start the project because it is only 10 miles long, does
not share tracks with other lines and was already due for
equipment upgrades. In 1999, the agency awarded a five-year
contract for the new signaling system to a consortium led
by Siemens Transportation Systems.

Kevin T. O'Connell, the chief transportation officer for
subways, said representatives from seven departments within
the agency were overseeing a rigorous safety plan with help
from an independent consultant, the Battelle Memorial
Institute, a scientific testing and research organization
in Columbus, Ohio.

The agency plans to begin running computer-operated trains
on one section of the L line in so-called shadow mode, with
a train operator still in full control, in April, Mr. Smith
said. The rest of the line would switch to that mode in
three phases, and fully computerized service would take
effect by late July.

Using radio frequencies, the new system will prevent
speeding, open doors automatically, allow engineers to
pinpoint the location of each train and eventually allow
for a public-address system that will clearly inform riders
when the next train is arriving, Mr. O'Connell said.
