Oui c’est ça. Si l’achalandage de la ligne Mascouche augment, le REM peut avoir une rame vide qui attend la ou j’ai dit pour les usagers d’exo. C’est improbable que ça soit le cas des la mise en service, mais c’est comme ça que l’infrastructure est conçu.
« Une rame vide attendra » et « Il est prévu qu’une rame vide puisse attendre éventuellement » c’est différent mais tout est clair, merci @twix24 pour l’info!

How would that work, it would just be inserted into the regular flow and increase the frequency between CdL and Brossard temporarily? And it wouldn’t work for the return trip, because then everybody would have to leave that REM train and catch the next one if they wanted to continue on their way west…

It would not be needed for the return trip. Only when hundreds of people arrive at CDL at the same time.

If only exo15 attracted enough riders!

Je pense que cette nouvelle connexion rapide vers le centre ville même si elle implique un transfert ramènera des passagers sur la ligne… Faudra par contre, un jour aussi s’interroger pourquoi les bus de la STM ne sont pas mieux arrimés avec l’horaire des trains (je pense à Pointe-aux-trembles notamment).

Je sais que ça se fait à Répentigny. Il y a un groupe qui travaille à faire la coordination si je me souviens bien.

That answers the second part of my question… 
And after that first extra empty train fills up, what then? Where does the next empty train come from? Do they just kick everybody off who were going north/west?
Or are we suggesting that Mascouche only has like five trains during rush hours, and maybe only one that will have enough riders to overflow an already-packed REM train?

Maybe short running, in that hypothetical scenario, or an empty train slotted in between other trains from Brossard or Saint-Eustache.
I imagine the train could do CDL-GC and it will stop at every stations. A message will say “ this train will terminate at GC”. Then go back to CDL empty and without stopping at any station.

In the morning peak, an out of service train (or in service, who knows) will come from Brossard or Gare Centrale and park itself on the right hand side of the left platform. Meanwhile, for all the morning peak, southbound trains will use the leftmost track and platform. Northbound trains are unchanged. Then, once the mascouche train arrives, the parked train returns south as an A1 train like normal. If mascouche say doubles or triples in ridership with the added convenience of the REM connection, or if the government actually invests in the mascouche line and gives it better station placement and frequencies, then they might have to put this system in place.
It’s a pretty good solution for the challenge of the Mascouche line. Obviously you can’t have maybe 500 riders get off a mascouche train, walk to the montreal bound platform, and attempt to board a train that may or may not be at crush capacity from demand in the north west.
What’s the max speed through turnouts for the west platform? If they are a limiting factor in trains’ approach or departure speed, couldn’t the empty trains approach from the north (presumably from Saint-Eustache garage) and occupy the westernmost platform instead, leaving the centre platform open for a more direct routesetting for through trains?
That is probably equally possible too. Just depends on whether the empty trains sit at St Eustache or Brossard.
If the trains come from the south, they can be in service the whole time and only 1 off peak direction train will be missing for one of the branches. If it comes from the north, the train would have to be out of service.
J’imagine que ce pourrait être utile aussi pour ceux qui viennent de la ligne bleue, dans les deux directions. Plusieurs ne vont plus transférer sur la ligne orange mais se rendre à E-M. Il risque d’y avoir un goulot d’étranglement là aussi. Donc, on envoie des REMs presque vides pour desservir la clientèle de la ligne bleue qui se rend à McGill ou GC. Est-ce possible d’avoir certains trains qui font des allers-retours entre GC et CDL?
Les allers-retours, de ce que j’en comprends, ne sont pas prévus: autant profiter de la capacité du tronçon central pour assurer une fréquence sur les antennes.

Pas prévu mais ça peut être utile si Montpellier ou du Ruisseau est hors service.
En effet, mais ce serait jusqu’à Brossard et non jusqu’à GC dans un tel cas.
