This excellent thread about Little Benton Sidings has both answered many questions about my trainspotting days and also set me on a search for more information. Memories fade after 55 years and although I trainspotted in the area of the 'Powder Monkey' many times, I no longer recalled the sidings. Selective memory I guess, and as you say John our desire to 'cop' a new engine number meant our focus on the ECML, and in the gaps between, riding around the Powder Monkey tracks on our bikes, the equivalent of BMX in more recent terminology.
With the help of the National Library of Scotland website, I easily overlaid the OS Map from the 1960s with a satellite image, and this has helped me greatly to picture the area once again. Included are the Rising Sun Colliery tracks also now long gone from the 'Rising Sun Country Park', and the High Farm housing estate, and the Jubilee School which we attended.
My sister bought one of the houses in 'Cheviot Court' newly built in 1982, and on many visits over the years I stared out of the back bedroom at the evolving ECML and could not quite picture where the Powder Monkey had been. This map image solved the issue for me. My sister's house is near where Little Benton North was, and the view from the upstairs window would have looked directly onto the signal box and farm bridge, which no longer exist. The sidings are now completely replaced by vegetation, trees and shrubs, and these effectively screen much of the ECML action, and with the electrification there is no significant noise.
Many thanks to you John, for such a stimulating subject for your layout.
