Hawaiian Railroads

In the 19th and 20th centuries, Hawaii had numerous narrow-gauge railroad lines on most of the islands.  Primarily these carried sugar cane from the field to the mill, but many also carried cargo and passengers.

They have a fairly good record of what types of engine and cars were used, so a historical recreation of the railway (e.g., in VTP) should be possible.

The narrow-gauge lines also have a bit of historical documentation, although it is scattered about.  For example, many of the cars went back to the mainland, as with the Kahului Railroad Company's No. 12 which ended up on Georgetown Loop, Colorado.

There is a single book, Railroads of Hawaii: Narrow and standard gauge common carriers by Gerald M Best (1978), which is now out of print, rare and expensive.
