Reid Newfoundland Railway 4-6-0 "Ten-Wheeler" Type Locomotives

Class 120 / F-3 (Locobase 3225)

1921 Railway Age (Vol 70, #16) noted that this railway required engines that could operate on 50-lb rail laid on grades of up to 2% and curving up to 14 deg. The main line ran from St. John's to Port-aux-Basques. These were the standard passenger engines until 6 Pacifics arrived in 1921.

Class F-3a (Locobase 4568)

Data from CN NFD Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.
