This picture shows TTC 4063 under (I believe) Landsdown carhouse. I think the car derailed on a curve going into the carhouse and, literally, "brought down the house". The date is 1947 or before, as the car was scrapped in '47. It was the first PCC to be scrapped in the world. I've seen a picture where the back end of 4063 was used to replace the rear of another car.
