This page covers N-gauge model railway products issued by Tomy before it created the Tomix brand name. Their history is not entirely clear, and what is presented here is what I know about them.
The early Tomy locomotives came in yellow-bottom flip-top plastic cases, with cast (raised) black lettering including "TOMY." Later, these early locomotives came in similar black cases cast with raised gold lettering. Still later they came in blue cases with silver lettering with both "TOMY" and "TOMIX." Some of these locomotives appeared in the first Tomix sets. The plastic cases and some of the locomotives are cousins of early Bachmann products sold in the U.S. The production in Hong Kong seems to have been shared with Bachmann. (The 1977 Tomix catalog even includes a section for American Bachmann items like Amtrak Metroliner MU cars and Auto-Train lococmotive and coaches.) The early drive is not as refined as in later Tomix locomotives. I have indicated the first year of manufacture, where I know it.

HN-503-3 DD-13 Diesel Locomotive - Here is another variation of the DD-13, blue with yellow end "wings." It is unclear what the "-3" suffix in the product number denotes. |

HN-504 Plymouth WDT Diesel Locomotive HN-505 Plymouth WDT Diesel Locomotive HN-507 Plymouth WDT Diesel Locomotive This U.S. industrial switcher design was also sold by Bachmann for decades. While the model is called an "MDT," that Plymouth version was a four-wheel design. The WDT was the six-wheel version. This photo shows the Tomy HN-504, the HN-505 and the HN-507 from top to bottom. The red and grey paint scheme was a Japanese National Railways standard, while the brown scheme was indicative of maintenance-of-way or construction assignment. |
