REM cars’ tests between Saint-Eustache and Sainte-Dorothée

Nature of the tests
Our teams are preparing the track to welcome REM cars for a second testing sequence. Starting May 4th, when all conditions are met, it will be possible to see the REM operating at low speed between the Saint-Eustache maintenance center and the Sainte-Dorothée station, except for one day when higher speeds will be reached. 

This exercise will make it to validate the components of the cars and test both manual and automatic driving modes. These are necessary steps to prepare the network for the beginning of tests, scheduled for spring 2024.

A team will also be on the tracks between 6 PM and 2 AM to test, among other things, the emergency telephone systems. It will be possible to hear backup alarms from the vehicle on the tracks, as it is impossible to make a U-turn. The vehicle's reverse mouvement will be minimized by the team in place.

Please note that for safety reasons, it is strictly forbidden for any unauthorized person to enter the tracks under penalty of prosecution.
Tests at 100 km/h for one day only
For one day only, from 6 a.m. to 6 p.m., REM cars will travel at a maximum speed of 100 km/h to validate some of their components and to obtain a preliminary estimation of the sound effects of their passage using sound meters installed nearby. These high-speed runs will take place in the Laval-sur-le-Lac area. An operator will be always abord the car.

Regarding the control of sound impacts
The arrival of the REM cars may raise questions about the noise caused. In this regard : 

1. An analysis is underway to confirm that the noise reduction measures already installed on the network respect the sound limits. 
2. The acoustic grinding of the tracks, which serves to reduce rolling noise, will be completed before the start of the tests scheduled for spring 2024.
