MBTA dealing with faulty ties on commuter line

Written by admin

Concrete ties on the Old Colony commuter rail lines are wearing out far faster than they're supposed to, a spokesman for the Massachusetts Bay Transportation Authority acknowledged according to the West Bridgewater Times. The lines -- Middleboro/Lakeville and Kingston/Plymouth -- have been found to have 4,000 ties that need to be replaced, said MBTA spokesman Joe Pesaturo.  

The ties, which are
attached to the rail tracks, have been supported by wooden ties and are not a
safety risk, Pesaturo said.

 

"It’s very safe,"
he said of the two rail lines, which he said see a combined average of 20,000
riders per day.

 

The ties were only
installed 10 years ago, but are supposed to last "decades," Pesaturo
said, declining to be more specific.

 

The Old Colony lines
include stations in Brockton, Bridgewater, Middleboro, Abington, Whitman and
Hanson. The CommonWealth article indicates that the tie problem is the most
serious in the Bridgewater and Middleboro areas of the line. The article
suggests that the problem could mean that all 150,000 concrete ties have to be
replaced on the lines, which would be difficult for the cash-strapped MBTA to
afford.

 

So far, however, there are
no other ties that have been identified with problems on the Old Colony lines,
Pesaturo said, emphasizing that the problem has affected a small portion of
ties.

 

"To date, we are
talking about approximately 2.7 percent of all of the ties on Old Colony,"
he said.

 

"100% of the ties have been
inspected numerous times and the inspections continue," Pesaturo said. "The
number of failed ties continues to grow at a rate that is expected. We are
investigating new methods to identify problem ties before the cracking becomes
visible to the eye, and we have had some success. This will allow us to predict
the further degradation of the ties. We are continuing to take actions to
replace failed ties before they adversely affect our ability to run trains. We
are replacing concrete ties, adding wood ties in the cribs and installing gauge
rods. We expect to begin work later this season to get rid of the highest concentration
of failed ties. Although the ties were all installed at roughly the same time,
there are still large sections (some almost 10 miles in length) that have
virtually no tie failures evident.

 

"The MBTA has engaged a
legal team to invoke the terms of the warranty that was part of our purchase
but we will not discuss details of our legal strategy," he said.

 

The MBTA has Rocla concrete
ties on the Greenbush line and Amtrak has both Rocla and non-Rocla ties on the
Northeast Corridor located on MBTA property. Further, the MBTA has non-Rocla
concrete ties on the Lowell line.

 

"Amtrak is dealing with the
ties on the NEC," he said. "The Greenbush and Lowell ties are of a different
design from those that are failing and they are showing no signs of any
problems. The Greenbush ties are newer than the problem ties and the Lowell
line ties are older than the Rocla ties showing problems."
