These two 0-4-0t steamers apparently have about half the water capacity of equivalent H. K. Porter & Co. tank engines, and the fuel is apparently carried over the boiler---something United States locomotive builders never did due to the bunker-fire threat. What insulation is used in the fuel bunkers against this fire hazard?

@bcschmerker I'm not aware of any extra insulation (other than the usual lagging around the firebox). As the fuel is coal the risk of ignition is less than wood (though B Class tanks were used elsewhere with wood firing).

@bcschmerker There is none as far as we know. Coal has a very high ignition temperature, around 1200 degrees. Steam under pressure at 180 PSI is only around 400 degrees. I could understand oil fuel not being carried over the bunker but for coal it doesn't matter. The main issue with the boiler bunker is that it requires an additional person standing in the coal bunker breaking up the coal and making sure it is funneled down the chutes to the cab.

Love the old-school health and safety.
