Patented track, also known as hard track, dates back to the mid 1800's.

The track was not patented, the manufacturer owned the dies to roll the track.

It was nicknamed hard track, flat track, because it was rolled from high carbon steel and the wheel bearing surface was flat.

Manufacturers include:

  • American Monorail
  • Cleveland Tramrail
  • Louden*
  • Spanmaster
  • Trambeam
  • Twin City

 The track can be identified by the width of the bottom section (running surface)
