FIREPROOF RAILWAY CARRIAGES.
In the United States, where a train on fire is no uncommon occurrence, asbestos is largely used as a lining for railway carriages. The method adopted is simply to pack three or four inches of asbestos between the floor proper and a- false bottom. and since this mineral wool is not only non-combus-tible. but also an excellent non-conduc-tor, it subserves a double purpose—protecting from fire and also from cold. An inch lining of asbestos on all other parts of the carriages greatlj* adds to their comfort, and keeps out both the cold draughts of winter and the heat of summer.
