Does any one know why some Birneys had the poles mounted on little lattice towers? The one in the photo below is Eastern Massachusetts Street Railway. Later, some of these were sold to the Concord (NH) Electric Railways and ran to Whites Park, near where I used to live.
The Waterbury and Milldale line in Connecticut, which ran two double-truck Birneys, had each pole mounted on its own little tower. Was it a safety thing? Or was it just to reach the wire? Thanks for whatever light you can shed on this.
