Montreal's commuter-train agency held a public meeting in Pierrefonds on Tuesday evening in its latest attempt to try and mend its relationship with passengers following a winter of delays and breakdowns.

The Metropolitan Transit Agency held the second of two meetings to reiterate that it's adding tracks and new train cars to curb overcrowding as well as heated switches to stop cold-weather equipment failures.

Most of the problems were on west island lines, much to the chagrin of passengers in attendance at the meeting.

AMT President Joel Gauther says commuters should be patient because changes are coming soon.

"We have a plan," he said.

"We know that for the major infrastructure it will take maybe 18, 24 or 30 months."

Aside from the news cars and switches, new train sheds will be built for the Two Mountains line to prevent equipment from freezing.
