Model MLW (ALCO) S-3

The Canadian produced S-3 locomotive is nearly identical to its U.S. sister model, the S-2. The main external difference is the sharp 90 degree angle where the top of the hood meets the front on the S-3, and the rounded front of the hood on the S-2. Also, number boards are located on the front of the S-3 hood, and on the sides of the S-2 hood.

This author is not aware of any commercially offered S-3 models. Updates to the webmaster are most welcome. However, for most modelers, the S-2 is close enough.
