This is an OUTSTANDING museum dedicated to railroading in Canada. I visited during the fall season so the grounds were very quiet. I spent 5 hrs. on the grounds, but then I try to read the placards and write down the information pertinent to the photo taken. Because I visited on the tail end of the season, only a streetcar was running the grounds and also the miniatuure train. One note, only a few of the rolling stock are open to the public but what one can view from the outside only seems enough to get a good idea of the conditions within. I visited the museum by taking a commuter train to Saint-Constant stn, and walked next door to the museum. As for the return trip, I chose the option to walk to an autoparc next to a shopping center, about 35-40 min walk, and caught the CIT Roussillon bus 130 back to centre Montreal. If you are interested in trains, then you have no reason not to experience this remarkable train museum. PS The museum sells a compendium of the collection which is more or less up-to-date.
