Notes:

-Only 30-inch gauge 2-6-6-2 built by Baldwin

Summary:

An interesting locomotive among Baldwin's many 2-6-6-2s, the tiny "Milan" was built in 1908 for service at the Angelina sugar mill in the Dominican Republic. In its technological features "Milan" was a very typical Baldwin Mallet of the time, using saturated steam and slide valve cylinders. Being built in 1908 it was also Baldwin's first attempt at designing a small 2-6-6-2 for use on industrial railways.

The "Milan" worked hauling trains of sugar cane for the Angelina plantation north of San Pedro de Macoris for an unknown amount of time. At some point it was scrapped.
