Pacific Great Eastern 2-8-2 "Mikado" Type Locomotives

Class Details by Steve Llanso

Class 160 (Locobase 31)

Data come from the 1947 edition of the Locomotive Cyclopedia.

Right at the end of World War II, the PGE bought a pair of Mikados (works #2286-2287); 2 1/2 years later the CLC delivered two more (2408-2409). The design displayed a long stroke for its cylinder size and all-around small dimensions. None of them had a long career as the PGE dieselized in the 1950s. 161 took itself out in a boiler explosion in September 1951. The other three were retired in 1956 with the latter two being scrapped that year and 160 retained for 6 more years before it was scrapped..

The Pacific Great Eastern (PGE) was intended to be the unifying transportation element for the province of British Columbia. Mike Cleven of the Cayoosh website noted above comments: "Originally begun before the Great War of 1914-18, the line was assailed by its critics as a line 'from nowhere to nowhere', running as it did in its first phase only between Pemberton and Lillooet."

Pemberton lies on the Lillooet River just north of the Lillooet Lake in a wide valley separated from most of the rest of BC by mountains all around. After World War I, the PGE extended southwest toward Vancouver, reaching Squamish (then called Newport) and extended to the Cariboo and Prince George. By then, the line was close enough to the Vancouver area that travellers from Vancouver took ferries from the Vancouver waterfront to connect to the rail line. It was only after World War II, however, that the railway reached Vancouver to the Pemberton Avenue Station in North Vancouver.
