Temiskaming & Northern Ontario 4-8-4 "Northern" Type Locomotives

Class 1100 (Locobase 2295)

Like the TP&W H-10s, these Northerns are little known and far lighter than the average for the wheel arrangement. They moved passenger trains along the T & NO's mainline from North Bay to Hudson Bay. In 1946, the T & NO was renamed Ontario Northland, although the numbering on these very northerly Northerns remained the same.
