In a comment to last Wednesday's post, Yury asked what a wayside post with an R means. Posts marked W are whistle posts, cuing the engine driver to signal as he nears a crossing. I'm asking about the R posts on a couple of railfan sites, with no results yet. Anybody here have a theory?
The whistle post shown below is one of two on the outbound side of the trail less than half a mile from the Bedford end at South Road. The R post is on the outbound side as the trail parallels Valley Road in Lexington, about one-third of a mile from the bridge over I-95 / Mass 128. [Update: The post is exactly 2000 feet from the bridge, as nearly as I can measure with the Gmaps Pedometer. That round number makes me think they're related.]
Today: 13 miles. This year: 154.3 miles.
