... on main lines - +50% on non-main lines according to the same source. I'll leave those more expert to explain the difference between the types of lines.
I am in no way an authoritative figure on railways.. my hire on date was September 2017. So please keep that in mind, I can and do make mistakes and I am continually learning intricacies of the rules I did not know before. Any rate I will try to explain.
Main track is basically anywhere the RTC (Rail traffic Controller) can tell you what to do. Either through OCS, ABS or CTC authorities.
Non-Main Track is 105 territory, that includes yards, dark sidings and industries.
If you follow this link, click on definitions and it will better explain Main track and non-main track. https://www.tc.gc.ca/eng/railsafety/rules-tco167.htm
Also I may have missed this earlier if it is 12 derailments in Canada since December on Main track only.. that could be correct. Non-Main track is were the majority of derailments happen (in my experience as well as by these statistics to apparently).
Any rate that link is to the authoritative source for railway rules in Canada. So if anything there contradicts me, I am wrong.
