    Yes, I'm sure you are correct. They mainly publish profiles on military aircraft and AFVs. I suspect the BR86 and BR52 were only added because of their use by military modellers in war time dioramas. I can't think of an example, but there are one or two other guesses in the book.

    Weird name change by the way! :))

    I'd love to find some of that wet coal that supposedly burns better :eek:

    That said, I've seen the coaling plant in operation at Grosmont on the NYMR and as they drop the coal, a water spray is activated that I assume is to to keep the dust down. It's quite a heavy damping and the coal must be wet, but it still burns. But burning better????

    And that's all it does, keeps the dust down.



    Coal dust/powder......as is any powder actually, wood, custard, flour, sugar....is highly explosive in the right conditions.

    There are probably as many theories about burning wetted coal as there are coal types. Decades ago when enjoying footplate rides, one fireman reckoned dampening the coal made it burn better. Perhaps this was a measure of increasing spontaneous combustion?
    A Japanese power generating station stores imported coal in the ocean, but that might be as a strategic reserve possibly.

    indeed, grain store explosions seem to be a feature of prairie life, and closer to home too.

    Tilbury Port explosion badly damages grain terminal silos Grain store roof mangled in 'massive explosion'

    Probably got a lot to do with the prohibition notices for locos on GW coal stages

    I must admit, I’d never heard of a custard powder explosion, but live and learn...

    Thanks Steph,

    as I said, live & learn.

    “the great Banbury custard explosion” has a certain ring to it, a bit like the “London beer flood“ London Beer Flood - Wikipedia
    Would be funny but for the poor victims...

    We lived until recently very close to a working water mill which continues to grind flour to this day as a tourist attraction but also commercially. I've spent many happy hours chatting with the miller and he always said that there are certain principles which have to be applied due to the potential for the dust created during grinding spontaneously combusting. Mind you, the mill has been there since the mid 18th Century so they've probably got it sorted by now.

    Combustion of coal in one of Titanic's bunkers played a part in her sinking. Apparently, the bunker was on fire when the ship departed Southampton, and on the side which struck the iceberg.

    I’d read that too. It rather begs the question of whether ships often sailed with their bunkers, if not alight, then at least smouldering. Wikipedia suggests that spontaneous combustion of damp, ideally fresh, low grade coal is certainly possible.

    Yep, it wasn't uncommon. It was also a problem at facilities like coal-burning power stations...

    Years ago, I worked as a coal trimmer in the power house at the distillery in the town. The power house had three chain grate Babcocks boilers and was kept coaled each day from 16T mineral wagons. But there was an emergency pile of coal to the side of the power house and I remember that being a constant worry because it would regularly ignite.
