I have found a couple of videos, that are not railway related but worth a look. They feature the river Thames which I remember as a young lad with much affection. The river was so busy in those far off days with tugs and lighters and larger ships down river in the dock area. I was fascinated by the lee boards on the sailing barges which were still in use in the fifties.
Today to my mind at least the river is rather clean and clinical nowadays and not nearly so interesting with most of the traffic being glass fibre river busses.
I was first taken on a trip to Greenwhich in the mid fifties by my father on a river bus from Charing Cross pier. There was a commentary on the boat pointing out things of interest I seem to remember. The whole river was alive and bustling with craft of all sorts from the flat iron colliers to small river tugs towing strings of lighters.
Both films are well worth a look as they show scenes that cannot be seen today.
My apologies if this has been posted before.
