I found an article in this morning's Le Soleil about a potential project in the Gaspe peninsula. My French is not good, but it appears that NGL Supply and Gaz Propane Rainville are looking at putting a propane terminal in Sandy Beach. This is basically at the end of the Gaspe rail line in the town of Gaspe, where port facilities already exist.
It looks like it will be headed to an environmental assessment, for implementation in 2010-2011.
The article talks about traffic of about 3,000 rail cars per year, which would be great for the line.
