Some quick highlights:
-In 2019 they replaced a pier by Davies station. (To me this indicates they had concrete issues with the piers right off the bat and absolutely gambled that the rest would be OK rather than redoing)
-In 2019 part of the concrete on Tawatina bridge deck had to be replace
-Also in 2019 Quarters tunnel concrete wall lining had to be redone (and there was some sort of serious safety issue as well, which aligns with what I heard about the tunnel construction management)
-In 2018 they had to stop work on the Churchill connector after they accidentally cut rebar in the existing Churchill station
-2022 traction power substation didn’t meet the Canadian Electrical Code
-The City was concerned about TransEd’s financial situation to the point they contacted the Feds regarding it
