An unusual device looms over the trail just west of the Lexington Depot (now home of the Lexington Historical Society). The first photo shows the dangling metal tines that brushed the tops of rail cars arriving at the depot. The second photo shows that the mast holding the boom and tines is a section of railroad rail mounted vertically. As that mass of metal makes an excellent electrical ground, I'm guessing that the purpose of this was to remove static charges from the cars. I wouldn't expect all-metal cars (such as #6211, now at Bedford Depot Park) to need this, but maybe other styles did. Does anyone here know more?
