Notes:

This item was produced from 1946 through 1956, in two variations. The rarest variation, which was produced in 1946, has brass strips in the wheel channels of the crossover plate; a feature that was discontinued in 1947. The brass strips were originally thought to correct loss of tender wheel contact while crossing the diamond. However, it did not work well after the contacts got dirty. The common variation was made from 1947 through 1956. In addition, the 1946 model has blackened rails, which did not appear on a #725 after 1946. Starting in 1957 the part number was changed to 26745, which can only be differentiated from a 725 by the number on the original box. There is one difference in the crossing that the Greenberg and Doyle books have failed to mention, and that is that some of the early units have wires that connect the track sections while other have metal strips.
