Hawaii Railway Co 2-4-2 "Columbian" Type Locomotives

Class 5 (Locobase 6749)

Data from http://www.ironhorse129.com/Prototype/ (visited 12 August 2005). Works number was 58686 in September 1905.

In addition to serving the Hawaii sugar plantations on the Big Island that was its original reason for being, #5 also carried passengers. Service gradually ground to a halt in the face of truck competition, shutting down completely on 29 October 1945.

Another source -- http://www.geocities.com/piersa2001/history.html -- says that #5 cost $11,901.25

Later, it was sold to the Tahoe, Trout Creek & Pacific Railroad. As part of preparing to participate in the big 1999 California Railrair, #5 received a new, ASME-compliant boiler and a complete overhaul; details available. This made the engine more attractive for tourist railroading and in 1999, #5 came to the Connecticut Agricultural Museum where it runs each fall.
