    [QUOTE=Sausage;RE the coal wagons: Did they manage to 'design away' those freezing gremlins with later designs? I'm wondering whether coal drops worked for other sites such as Drax??.[/QUOTE]

    No! If one looks at the HAA wagon side on; you see that the wagon is basically 3 separate opening door units at under frame level, joined onto the full hopper body. One of each pair of doors was opened/closed by the trackside opening/closing mechanism; the other door in the pair was was opened and closed by the actions of a bloody pair of great horns - that were welded to the centre line of the inner surface of each pair of door and stuck up into the centre of the body. A receipt for disaster - the prototype wagon was tested with hand mined coal and worked perfectly. Unfortunately the mechanically mined coal from the new deep mines was much finer (what my Dad used to call 'slack', when complaining about our domestic coal delivery when I was a lad) and as it had to be washed to remove the dust, it retained a lot of water. This residual water froze when the winter temperatures dropped below freezing, and discharge of the load was impossible as the door 'horns' could not cut through the frozen load of coal. So at a time when the power stations were calling out for as much coal as possible - There was a bloody great shortage. Stocks that had been put to ground stocks was difficult to handle, because that froze and was difficult to handle with the equipment available on site. In the days of the old 16 Ton coal/mineral wagons, freezing was still a problem, but many of these wagons were discharged by tippler systems. The sight of a 16 ton frozen block of coal falling from an inverted wagon into a tippler discharge hopper was both a sight to behold and a ground shuddering noise to hear. As I have said earlier; the system put in place to correct the Merry Go Round cock up meant that there was far more ready mined coal available at the start of the miners strike and the envisioned sudden black out did not occur as envisioned. Hairy times to have worked through, all the same!
