Inverted T

During the 1960's, a new design for monorail was in prevalent use for small amusement parks and zoos. Developed and sold by Universal Design Limited (UDL), the guideway resembles an inverted T when viewed in a cross section diagram. The vertical element of the guideway are only used for guide wheels, while the lips at the bottom of the track carry the load bearing wheels. While many UDL monorails were installed, no large scale systems made it off the drawing board. One was proposed for the Seattle Monorail, but the Alweg system was selected there.

Today several companies are promoting various versions of the inverted T monorail for transit.

Inverted T system proposed for 1962 World's Fair.
