Why a study for the NORTH side?

No Beaconsfield administration headed the protection of the health of residents on the north side

On the north side, the noise problem is caused by the trains. The MTQ measured noise in 2010 but did not offer any solution because it is not responsible for the rail network.

Built UNDER the rails

The MTQ realized this as early as 1987 and in 2010, and that was its reason for not proposing a solution for the north side.

“North of the highway, rail traffic strongly influences the daily variation in noise levels since the tracks are very close together. Noise levels fluctuate more significantly, mainly at night with the passage of freight trains. » P.13

“North of Highway 20, in the territory of the city of Beaconsfield, there are no areas where the noise generated by highway traffic reaches or exceeds 65 dBA (…) Noise from the passage of trains from freight and commuter trains is a sound source comparable to and even superior to road noise. » P.15

MTQ 2010

The shrill noise of the rails wakes residents up at night.

These trains run on diesel and therefore also pollute residents’ air.

Measurements taken by the MTQ on Elm St. in 2010. Note that 65 dBA is the threshold to mitigate according to the WHO and the MTQ and many other health organisations.

Almost 20% of the city’s population lives less than 300 meters NORTH of the highway 20

Within 300 meters north of the train tracks, there are residents, students and teachers who are assaulted at least 8 hours a day, 200 days a year:

  • At least 1,150 residences * 3 = 3,450 residents (excluding new constructions (Adamus, and Westcroft)
  • 1 primary and secondary school (207 students, 50 employees)

NORTH: More, longer, noisier and more dangerous trains

There are 4 tracks splitting Beaconsfield, two for CP and two for CN.

Four (4) train rails across Beaconsfield

Trafic on CN and CP tracks in Beaconsfield are estimated (p.4) at more than 36 freight trains per day and 47 passenger trains per day on week days.

Rail traffic on the north side has at least doubled in 30 years. On page 115 of the “Schéma d’aménagement of the city of Montreal” (2015), we note:

“In recent years, we have seen an increase in traffic and in particular in hazardous materials in Montreal, as well as across Canada. This situation raises concerns about the health, safety and general well-being of the population. » P.121

No noise study north of the 20

Residents on the north side of the A-20 highway in Beaconsfield have been orphaned for a solution long before the highway was transformed.

  • Several residences and apartment blocks have been built too close to the rails (within 300 meters).
  • Many reside UNDER THE RAIL LEVEL

However, several scientific studies show that railway noise is at least as serious an issue as road noise. An expert report cited in INSPQ 2015 concludes:

“There is strong evidence that the use of well-designed noise barriers is effective as a method of locally reducing transport noise because, based on a before and after efficiency measure, they reduce noise between 5 and 12 dBA. » P.72

“Installing 3 to 4 meter high acoustic barriers can reduce railway noise by up to 15 dBA. P.234
