SPRING TRAINS + RÉSEAU EXPRESS MÉTROPOLITAIN REM test and two EXO trains

On the observatory of Pointe-Saint-Charles we see that there is a REM train of 4 cars being tested on the surmounted tracks. Also, we see two EXO trains traveling in opposite directions through the Pointe-Saint-Charles maintenance yard. In the foreground, we see that there are two MR-90 trains (Type 400) which ran on the old Deux-Montagnes line and two lines of Comets II trains (Type 700) which used to run on the Candiac line parked in the maintenance yard.
