Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 4415)

Data from See also DeGolyer, Vol 79, pp. 377+. Works numbers were 60506-60507 in June 1928.

Plantation Moguls of relatively small dimensions. Rushton Improved cabbage stack dwarfed the steam dome flanked by two smaller sand domes. Its appearance suggests an early 20th-Century origin although it was in fact produced in June 1928. Two "Hereafter" notes suggested raising the question "as to re-designing frame just back of rear drivers to provide better support for fire box" and reminding the builder that "all springs are to be made extra strong on account of rough track."

War and later natural disasters took their toll on an area that had already seen a big drop in traffic and revenue. By 1988, the last line had closed.

The #2 later was cosmetically restored and put on display at the River Banks Commercial Center in Manila.
