Before World War I, locomotive manufacturer Baldwin and the C&P management discussed the building of a small articulated engine to work the Eckhart Branch. The catalog Baldwin 2-4-4-2 was rated at 44,200 pounds of tractive effort, and grossed 188,000 pounds. It was rated for 475 trailing tons on a 3 percent grade. It used wheels, and 200 psi boiler pressure. It was a Mallet design, with the high pressure rear cylinders rigidly attached to the frame, and the front low pressure cylinders pivoted, in the manner of a pilot. The high pressure cylinders were 19" x 26"; the low pressure ones were 29" x 26". Baldwin built at least two engines to this design for the Little River Railroad in Tennessee. The first was rejected, and eventually went into logging service on the West Coast.
