History

edit

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 driving wheels, a pair of 17 in x 22 in (431.8 mm x 558.8 mm) cylinders, a boiler pressure of 205 psi (1413.4 kPa), a tractive effort of 25,179 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 gallons of water.[1]

Accidents and Incidents

edit
  • 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.[4]

Preservation

edit

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