Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p 8. See also DeGolyer, Volume 48, p. 283 and a history of Bridal Veil Lumbering Company at Lewis & Clark's Columbia River - "200 Years Later"

"Bridal Veil Lumbering Company, Bridal Veil, Oregon",, last accessed 12 January2015. Works number was 39524 in March 1913.

The balloon stack indicates a wood burner and, sure enough, the fuel capacity of the tender is given as one cord. It's quite unusual for a North American locomotive in coupling an all-adhesion six-coupled locomotive to a separate tender.

Located at the base of Bridal Veil Falls in Oregon, the logging road shared with other such lines steep grades (7%), tight curves (29 deg minimum radius), and light rail (40 lb/yard//20 kg/metre).
