In case you've never seen this… EVG regular Pinhead shared this video… here's the YouTube description:
Hosted by the late transit historian Roger Arcara , we take a nostalgic ride up the eastside 3rd Ave. EL in the early to mid 1950's in color, which by that time was MANHATTAN's last surviving elevated line. Please note this film covers the line north of CHATHAM SQ. which is at the tail end of THE BOWERY, on up to the north Bronx. The section south of CHATHAM SQ was abandon in 1950. and this film covers the years 1953- 1955.
The video is 57 minutes long… you will find a few familiar scenes starting with Cooper Union at the 9-minute mark… up to 10:15… The 3rd Avenue EL closed in May 1955.
