Safety at the King Road Yard.

Condolences to the 3 engineers that were killed in the crash.  Train derailments do happen due to weather, extreme heat or cold can be a factor, but when an accident occurs in nice weather on almost the anniversary of another derailment 4 years before, it has to be more than coincidence.  Is there a faulty switch?  Does the track need repair?  Are the trains moving through the yard too fast?  I thought there was a speed limit through freight yards.  I know at Mimico there are signs about speed limits.

(Update: The train was speeding when the incident occurred, but was the freight train speeding 4 years ago when it derailed at the same spot? http://www.theglobeandmail.com/news/national/derailed-via-train-was-travelling-four-times-authorized-speed-limit/article2355102/)

These are all questions I would like to see answers on.  I take the Go Train and TTC and would like to know that the sections of track are safe.  If they are not then we need to be resolving those safety issues before expanding service elsewhere.  You may say CN owns the tracks but Go Trains and Via trains use them and should push for them to be a safe place to travel.
