- Train with Steam Locomotive, Passenger and Freight Cars, circa 1856 - Locomotive boilers had to stay hot to produce steam. Lagging -- insulation around the boiler -- was crucial. This American-type locomotive of the 1850s had narrow wooden strips mounted around its boiler for insulation. But the wood deteriorated quickly when exposed to weather and sparks. Improved designs placed a protective sheet metal jacket over the wood.
