English: 1876 Dalifol double decker Tram for 50 passengers, built by Forges et fonderies A. Dalifol in Paris following plans by steam car pioneer Amédée Bollée père (1844–1917). This tram was intended for the Compagnie des Omnibus de Paris which didn't weant it. This vehicle had a vertical boiler in front, all wheel drive by a steam engine for each of the four wheels; these were all steerable. It further featured independent suspension for all wheels by telescopic tubes, shaft transmission, and had a device that enabled leaving and reentering the rails. It operated fine when testing it, just needing rework of the shafts.
