The Baldwin Class 12-28 ¼ E was a series of 2-8-2 "Mikado" type steam locomotives that were built by the Baldwin Locomotive Works for several narrow-gauge railroads.

History

The class of 2-8-2 "Mikado" type steam locomotives were designed in the 1910s with one example East Broad Top #12 "Millie" being built in December 1911, where it was classified by East Broad Top as a Baldwin 12-28 E-1.[1][2][3]

But in the 1930s, an updated version was drawn up. This version had 44-inch (1,120 mm) driving wheels, a pair of 17-by-22-inch (430 mm × 560 mm) cylinders, a boiler pressure of 205 psi (1.41 MPa), a tractive effort of 25,200 lbf (112 kN) and weighed in at 72 tons without the tender (115.25 tons with tender). Their tenders could hold up to 8 tons of coal and 4,000 US gallons (15,000 L; 3,300 imp gal) of water.[1]

The locomotive class were often referred to as Hog by the crew members, due to their high fuel consumption.[4]

Preservation

Only four locomotives of the Baldwin Class 12-28 ¼ E are still in preservation.

Accidents and incidents

  • In 1940, 1951 and 1955, No. 70 was involved in three major accidents while working on the WPY, where it rolled over on its side three separate times.[11] The locomotive would be repaired three separate times after the incidents and would continue service.[11][12]
  • White Pass & Yukon Route No. 72 was involved in a roundhouse fire that had destroyed the locomotive in 1969 and its boiler was scrapped in 1974.[10]
