, New Jersey in 1886. It was built out of lightweight steel construction and had a great performance, but to circumstances unclear till now, was never expanded.

The design of the rail-frame appears to have influenced Eugen Langen, or his mechanicians in designing the first elevated tramwaz, as his Wuppertal Schwebebahn framing bear a remarkable likeness to the Enos construction.

, the inventor of the internal-combustion engine, and probably knew the Palmer Railway. In the nearby expanding industrial zone of Wupper Valley, entrepreneurs and governors were looking for a modern urban transportation system. A cooperation of politicians and businessmen from the Barmen-Elberfeld industrial area around 1890 ordered from the factory of Otto and Langen, now Deutz, an electric powered elevated railway system. The official name was Anlage einer elektrischen Hochbahn (Schwebebahn), System Eugen Langen Köln or Electrical Elevated Railroad (Floating tram) Installation, System Eugen Langen Cologne.

The installation and stations were built by three companies, among them the company of Friedrich Harkort. In 1901 the first track of the Wuppertal Schwebebahn opened, in 1903 it was extended to the final length of 13,3 kilometers. This system is still in operation as a normal means of public transport, moving over 20 million passengers each year.

A system of the same type, but much shorter, and the wagons being moved by a cable, powered from the mountain station, opened in Dresden, 1901.

 lines, the Siemens Company of Germany has developed a smaller scale system similar to the SAFEGE Monorail. and Aerorail of Texas and Sky Train of Florida are promoting steel-wheel versions of SAFEGE as well.

Japan would later adopt the Alweg and Safege monorail systems and build more transit monorails than any other country in the world.
