I imagine there must be quite the bottleneck between Pratt and Livingstone in B.C.'s Lower Mainland. Along with service provided by SRY, I’m guessing this is the route that coal and container trains use to get to Delta’s superport. How many rail companies use this route and what is the frequency of service for coal and container traffic? I think this is where local residents had problems with rail traffic effects on the enviroment, their lifestyle and on vehicle traffic.
It’s not as much of a bottleneck as you might think. The line is actually part of CP’s Page sub, although originally the route was part of the BCER interurban line (later BC Hydro, now SRY) to Chilliwack , and is used by CN and SRY as well as CP. SRY traffic is fairly minimal (one or two trains a day). The line does indeed handle CN’s and CP’s coal and intermodal traffic to and from Deltaport, but remember that not all of the coal and intermodal traffic you see on the main line is going to or from Deltaport–a lot of both is going to or from Vancouver proper (and to and from Surrey as well in the case of containers). I don’t know if local residents have had issues with rail traffic there–if I lived by the track and wasn’t a train nut, I might for sure.
