| Metra Improvements Upgrades
Steam Toward Completion by Craig Barner Commuter
rail service is expected to improve because of $558 million in upgrades on the
Metra system in the Chicago area.

Three of the system's 12 lines are seeing "New Start" improvements:
the 52-mi. North Central Service to Antioch, the 36-mi. Union Pacific West to
Geneva and the 33-mi. SouthWest Service to Orland Park. Each line terminates in
the Loop.
Federal Transit Administration New Start funding was approved
in 2001, and construction started in late 2002 or early 2003 depending on the
line. State and local sources are also providing financial support.
Increasing
demand and the expanding boundaries of the Chicago metropolitan area are driving
the work, said Tom Miller, senior media relations specialist with Chicago-based
Metra.
As part of the project, the SWS was extended about 12 mi. to Manhattan,
and the UPW is being lengthened 8 mi. to Elburn from Geneva. The NCS line will
not get longer but will receive additional track.
The SWS route will expand
from 16 to 30 weekday trains, and the NCS will grow from 10 to 22 weekday trains,
said Audrey Renteria, Metra media relations specialist. The busy UPW line will
not grow beyond the existing 59 weekday trains.
Ridership is also expected
to surge in part because of improved service.
Renteria said the SWS is
projected to go from 6,843 weekday boardings in 1999, the most recent figure,
to 18,500 boardings by 2008, and the NCS is expected to increase from 4,500 boardings
to 12,200.
These projects involve areas that are experiencing significant
population growth and economic development and are projected to keep growing well
into the 21st Century.
The SWS project was completed in December, said
Gary Pearson, project manager of Chicago-based F.H. Paschen/SN Nielsen, the general
contractor.
The others are expected to be done by year-end.
Adding
Track Each service runs on track shared with freight trains. Second or third
track that is parallel to existing lines will be added for improved efficiency.
The
UPW is getting third track between Geneva and Elburn. Thirteen mi. of second track
will be added to the NCS and 3 mi. to the SWS lines. Some freight trains exceed
a mile in length, and the additional capacity will allow for a passing line.
Nine
signal bridges are being installed on the UPW because of the new track, said Chuck
Straiton, manager of special projects in Elburn with Omaha-based Union Pacific.
The added track means additional safety measures are required.
"Trains
can be parked on both [outside] tracks, and the middle train wouldn't be able
to see any kind of signal," Straiton said. "With two tracks you have
outside signals, and with three or more tracks you have to have signal bridges."
The
projects also hope to relieve parking and pedestrian congestion at the stations
and ease bottlenecks on the lines.
Stations or platforms are being added,
expanded or upgraded.
Six terminals - one each in Chicago, Chicago Ridge
and Manhattan and three in Orland Park - are new on the SWS line, Pearson said.
On the NCS line, nine terminals are being renovated, said Jamie Rich, project
manager with Elgin-based IHC Construction Cos., the general contractor. Stations
in Franklin Park, Schiller Park, Rosemont and Grayslake are new.
There
are new terminals in La Fox and Elburn on the UPW line, said David Bergstrom,
project manager of Park Ridge-based Ragnar Benson Inc., a member of the Benson
Rausch Reyes Joint Venture, the general contractor.
By 2008, more than
800 passengers a day are projected to board at each of the new UPW stations with
parking.
"I've actually had residents come to the trailer and ask
if they could buy a parking space in La Fox," said Dan Jordan, project engineer
with Ragnar Benson.
Maintenance yards are being added in Manhattan for
the SWS and Elburn for the UPW.
A time-consuming train move from West Chicago
to Elburn will be eliminated on the UPW due to the yard there, Miller said.
The
existing West Chicago yard requires empty trains to shuttle west 3 mi. to Geneva
before starting their morning trips east into the city. This reverse move against
traffic flow is further complicated by track restrictions in the area that is
believed to be one of the busiest freight corridors in the United States. Tricky
Trackwork The railroads themselves have done the mainline trackwork - setting
the ties, limestone ballast and subballast and rails - because they own the lines.
On
the UPW extension, the laborious trackwork included setting an estimated 63,000
concrete ties, Straiton said.
The contracting team performed the trackwork
in the Elburn yard, which included laying 30,000 tons of subballast, 36,000 tons
of ballast and 4 mi. of track, Bergstrom said.
The intricate trackwork
process is carefully orchestrated to ensure that it is done properly.
The
process starts with laying a 6-in. layer of limestone subballast that is modified
to have a low number of small pieces, Jordan said. The rail is placed on the ties,
and the two are attached via clips.
A 2-in. level of ballast is dumped
on the track, and a tamping machine lifts the rail above the ballast. A laser
and target are used to align the track properly.
The rail is unclipped
and tensioned with heat to keep it straight, Bergstrom said. "If you're in
cold conditions like this, you have to heat the rail so it's a certain temperature,"
he added. The rail is reclipped, and another load of ballast is placed. Being
Civil A substantial amount of infrastructure work went
into the projects.
For example, 28 bridges and culverts will be upgraded
on the SWS between Orland Park and Manhattan. The piers, footings and spans are
being enhanced because Federal Railway Administration rules require a sturdier
structure for commuter trains vs. freight trains.
Cutting and filling was
done to prepare the Elburn yard because "you can't have grade deviations
or the trains will start rolling on you," Bergstrom said.
About 219,000
cu. yds. of soil were moved, and a drainage system was installed.
Wetlands
and other obstructions made the accessibility to some areas difficult.
As
a result, temporary roads and crossings were built on the NCS project where terrain
was poor.
Contractor employees were required to study a safety orientation
on the Internet, pass a test and carry a certification card. They retook the test
after a year.
Major thoroughfares - including Touhy, Dundee and Deerfield
roads - were shut when construction traffic got heavy on the NCS project.
"For
the most part the public has understood that we've got to do the work and get
it back open for their use," Rich said.
Another Metra project, the
$86 million replacement of 24 viaducts on the Rock Island District line, will
be completed in June. The viaducts between 18th and 60th streets in Chicago date
to the 1890s and need replacement in part because locomotives are heavier than
they were when the structures were originally built.
And the proposed 55-mi.
Star line would provide service between Joliet and O'Hare International Airport.
Few details have been announced because the project is still being studied. |
