Southern Quebec Railways after 1979

[Station Master]

Hi ya, folks. Seems every post I put up of late has to do with abandonments, but I need to ask for my files and for estimations of right-of-way conditions to explore. It's easy for me to do Ontario due to two reasons, there is a web site specificly on Ontario rail companies and I live in Eastern Ontario, frequantly exploring the abandoned routes. Here is my problem in Quebec, when were these abandoned and what were their sub names: (By the way....has the St-Remi Spur been abandoned yet?)

Cecile Junction to Lacolle (Valleyfield Sub)
Farnham to Granby (South Shefford Sub)
Marieville to Waterloo (Granby Sub)
Richmond to Charny
Victoriaville to St-Gregoire
Sorel to St-Gregoire
St-Hyacinthe to Bellevue Junction

Thanks all :confused:
