"Old 93" NYC Fire MuseumThis is another exhibit at the NYC Fire Museum. This particular piece is a 1912 steamer. Steam does not provide the propulsion, however. The propulsion is provided by a 1912 gasoline-powered Van Blerck Tractor. These pieces were common around the turn of the century, when the gasoline engine made its debut. Many fire departments, the FDNY included, made these hybrids out of concerns over the reliability of the gasoline engine in contrast to the well-proven reliability of the steam engine.

Many of these conversion tractors were in fact petrol-electric hybrids, with the gas engine powering a generator, which supplied current to either hub motors or wheel motors. One of these is also on display at the FDNY museum and is illustrated on this site. But horses continued to provide motive power for many FDNY apparatus up to 1922.
Germany and France also went through this transitional phase, but in the UK the change over to petrol powered fire engines with PTO-operated pumps skipped this step, although there were some battery-electric units in big cities like London.
