As a prototype, the SD40-2 was the most popular second-generation diesel with sales of over 3000 in the U.S. and more than 700 in Canada. There were many variations of this popular diesel because of the long production run.

Model Information:

The Kato HO SD40-2 Mid-Production features functioning ditch lights which can be switched between alternating (flashing) and steady lighting modes on-the-fly. You can toggle the alternating ditch lights as the locomotive approaches urban areas or road crossings on your layout, or elect simply to run them all the time, however you'd like to enjoy it.
