From the Toronto Star:
The project is expected to boost capacity on the rail line by eliminating bottlenecks and reducing delay-causing conflicts between passenger and freight trains.
Sections of new third line track will be added to the existing line at multiple locations between Oshawa, Ont., and Brockville, Ont.
A fourth track will be built at Via's busy Belleville, Ont., station.
This investment could go a long way to making train travel more attractive along the Toronto-Montreal corridor. I've been on many a train that has sat waiting for up to half an hour for a freight train to go by.
