Ah well, there’s yer problem, innit?

Boiler explosions are of a particular danger in (locomotive-type) fire tube boilers because the top of the firebox (crown sheet) must be covered with some amount of water at all times; or the heat of the fire can weaken the crown sheet or crown stays to the point of failure, even at normal working pressure.

    The loco pictured appears to have exploded at the end farthest away from the crown sheet?

    Water suddenly taking up 1760 times the volume.
    Amazing that that number is number of yards in a mile.
    Wonder how far the boiler front plate, smokebox door and headlight went.
    A most effective retro rocket brake.

    Excellent illustrations for Derek Lowe’s “Things I won’t work with”. Scary
