While G Train riders are accustomed to every possible permutation in terms of weekend service disruption, and L train riders (and more recently 7 Trainers) resigned themselves to enduring weekends without trains, people along the F Line have gotten a strong taste this weekend. A complicated set of service disruptions has basically left people depending on shuttle bus service along the F and G lines from Hoyt-Schermerhorn Street to Seventh Avenue in Park Slope. (Full explanation here, and best of luck understanding them in full.) Although the reality is somewhat more confusing than that and a walk down Smith Street yesterday afternoon would have revealed a lot of “ohs,” “huh?s” and some expletives as people looked at stations and then tried figuring out the shuttle bus situation. Meanwhile, there were dozens of buses lined up on Ninth Street in Park Slope tying up traffic and thousands of people pouring off buses at Seventh Avenue and Ninth Street to get back on the F and go toward Stillwell Avenue. The official reason is that signal work is being done, but there appears to be other work going on too.
