TTC's least photographed PCC could be #4063. This was retired after it went into an open switch outside of Lansdowne carhouse and rammed into the carhouse wall while on Lansdowne night car duty. This photo was taken in January 1947 by WC Bailey. The car was scrapped and Lansdowne became a trolleybus route later that year. Photo donated by Rob Hutchinson.
