In reading about the recent Transportation Safety Board (TSB) report (http://ottawacitizen.com/news/local-news...rain-crash) on the OC Transpo bus/VIA train crash in 2013 I was introduced to the concept of a "cross-product" threshold for determining when over/under passes should be built in place of level crossings.
From my understanding of the concept, if the daily number of trains passing through the intersection multiplied by the daily number of vehicles passing through the intersection exceeds a threshold of 200,000 consideration should be given to change the intersection to an overpass/underpass due to excessive risk of potential collisions.
That got me wondering what the cross-product of intersections locally might be and so I started looking at Park, Strange, Lancaster where they cross the CN line (GEXR). I have decent traffic volume, but I am struggling to figure out the train volume.
Does anyone know the number of freight trains that on average pass through that section of track on a daily basis? I think there are 8 passenger trains a day correct (2 EB VIA + 2 EB GO + 2 WB VIA + 2 WB GO = 8) and at least 2 freight trains.

Everyone move to the back of the bus and we all get home faster.
