After several days absence, I returned to find the crew hard at work, despite the snow and frigid temperatures. Before anything else could be done this morning, a thick layer of ice had to be scraped off the roadway. Then there was a good bit of work along the tracks, with regular cries of "Railroad!" (which always sounds to me a lot like Scoobie-Doo calling, "Ruh-Roh!"). Distances are being measured, lines are being drawn, and a huge pile of gravel is slowly being transported from street level to track level. The colorful banners took me by surprise at first: they seemed so whimsical and random; but on reflection, they make a lot of sense since they really stand out against the snow.
