637 at East 169th and Boston Road on May 2 1948. 637 ran on 59 St. X until 1946 then had poles fitted and on Tremont Av and So. Blvd until closure in 1948.
Not usually seen on Boston Rd. line but this does look like Boston Rd because of cattycorner intersections. Note T sign so maybe this car was deadheading
