Before Trix began manufacturing their N-Scale electric powered trains, they first manufactured a series of floor toys, trains which were rugged metal castings colorfully decorated, but just a child’s toy.
In many ways, they were the “pilot models” for the electric powered Minitrix product line since many of the same models would later appear in the Minitrix Electric line. These floor toys had free-rolling wheels without flanges and simple hook type couplers. They also were built to a proportion of 1:180 instead of the 1:160 of N-Scale. However, the research had been completed, so manufacturing in N-Scale was easy.
