more delays San Fran subway
Posted by blue streak 1 on Monday, November 16, 2020 8:08 PM

New from downtown to Chinatown.

announcement that tunnel worker delays due to positive CV-19 test and supplier due to CV-19.  Also wrong rail ?  Exactly what that is ?  Suspect that the supplier delays are actually the operative reason for the delays.

Subway now has ballast probems.  Seems that the rehab had the ballast reused which had high mud content and some heavy metals  Evidently will cause instability.  The heavy metals are  probably haz mat and disposal will be expensive.

Seems as if monkeys and footballs are being brought to mind.
