In recent years, models of many diesel locomotives not previously offered in O scale have been brought to market. Despite this great variety, there are still numerous diesel prototypes of which models remain to be offered. As a fan of New York Central, I'd like to see a model of the NYC Class DES-3. Also called the "Tri-Power", in addition to its 300 HP internal combustion prime mover, the locomotive was capable of operating off the Central's 600 volt direct current third rail as well as battery power, hence the reference to three potential sources of propulsion. Naturally, Class DES-3 locomotives were common in and around New York City in the electrified zone as evidenced by the photo of the 1547 at Harmon:
Given the limited number of the prototype which were built and the associated limited exposure, this is a model which may be well suited to brass construction in a small quantity.
There are many other models which I'd be interesting in purchasing but thought I should limit my initial post to just one type. What would you like to see? Please post away.
