The first appearance of AHM’s little HO-scale Plymouth MDT Switcher appears in the spring of 1965. The model original retailed for $5.95 and was presented in five road names: Illinois Central, Pennsylvania Railroad, Reading, Santa Fe, Union Pacific. In addition to this HO version, AHM also offered an N-scale, as well as O-scale reproduction for this industrial diesel in its catalog. This Yugoslavian-made model served many years in AHM’s line and similar models appeared in the catalogs of American, Train & Track; Bachmann; and TYCO.
