The line continued to struggle and the Interstate Commerce Commission urged the Union Pacific to take it over. In 1935 the UP acquired the LNP&W, and ran it until 1951 when it merged, the line becoming the Coalmont Branch of the UP, and the LNP&W depot in Laramie was closed. Shortline Wyoming Colorado Railroad bought the line in 1987, and subsequently abandoned it.
The Baldwin Locomotive Works received and order from the Colorado, Wyoming & Eastern in 1917 for the line's one and only "Mikado" type locomotive. It was delivered in 1917 and given road number 8. This locomotive had 48" diameter drivers, 20" x 28" cylinders, a 180 psi boiler pressure, it exerted 35,700 pounds of tractive effort and it weighed 187,600 pounds. The fire box was 178 square feet and the evaporative heating surface was 2,500 square feet. In 1917, Baldwin superheated the locomotive with a 536 superheater making the combined heating surface 3,036 square feet.
There are no surviving CW&E 2-8-2 "Mikado" type locomotives.

The LNP&W was merged with the St Joseph and Grand Island sometime in 1914, perhaps.
Baldwin took the earlier Mike design delivered in 1911 to the Laramie, Hahn's Peak & Pacific (Locobase 6580) and superheated it for delivery in 1917. (By now the LHP&P had gone into receivership and emerged as the CW&E.)
This was the result. An altered firebox disposed of the arch tubes, reducing the area. As usual the superheater contributed more than its nominal area to the engine's power. In this case, the relatively rare Southern valve gear distributed the steam through 10" (254 mm) piston valves.
