A friend of mine collects transport-related large format photos and post cards, scans them and posts them on Flickr. He shared an image of a weed-killing train, formed of superannuated loco tenders. I wondered if it was possible to identify the original company and tender from the image. Happily, it's a plate from a book called "The Permanent Way - Britain's Railroads in the Making", published after the Second World War. Here it is: My inclination is towards the East. Those buffers look LNER-ish. The blurry coaches on the left don't help, though there's a hint of a two-colour livery. So, let's open it to the wider WT Brain and see if we can work out some details.
