Anybody know, specifically, what's being done east and west of Woodside, literally 24 hours a day for the past several weeks? "Please no conjecture, if you don't know, don't speculate".
I tweeted at them the same question, the response i got was multiple projects, such as concrete tie replacement and signal testing.
It seems they are taking advantage of lower ridership and a weekend schedule to squeeze in more work. I myself have heard the work going on at various points in the day, including 6pm, 4am, 11pm. Etc
