Source-derived summary

Canadian National Railways U-1-f class locomotives were a class of twenty 4-8-2 or Mountain type locomotives built by Montreal Locomotive Works in 1944. They were numbered 6060–6079 by CN and nicknamed "Bullet Nose Bettys" due to their distinctive cone-shape smokebox door cover.

Construction history

The order for these engines came during World War II when steel was of extreme value. The mountain type locomotive was a step down in size from the much more prevalent Northern Type (4-8-4). As a result of this the mountain type had less power but more speed and served well as a general purpose workhorse.

Modifications

Half the class had been converted to oil-firing by October 1944. This resulted in the 18-ton coal/11,700-imperial-gallon (53 m3) tender being exchanged for a 5,000-imperial-gallon (23 m3) oil/11,000-imperial-gallon (50 m3) water tender. In later years several locomotives lost the distinctive cone-shaped smokebox door cover.

Preservation

Of the twenty locomotives that were built, only three remain in existence: 6060 owned by the Rocky Mountain Rail Society at the Alberta Prairie Railway, Stettler, Alberta; 6069 at Sarnia, Ontario; and 6077 at the Northern Ontario Railroad Museum, at Capreol, Ontario.

6060's restoration and run to Expo 86

In 1985 through to early 1986, Harry Home led efforts to restore CN 6060 and run it to Expo 86 in Vancouver.

Editorial summary

The public source identifies “Canadian National Class U-1-f” as class of 20 Canadian two-cylinder 4-8-2 locomotives. This brief keeps that definition visible, then builds a research path around Canadian, National and Class.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1944, 1985, 1986—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Canadian, National and Class providing the first useful test.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 20, 2026.

Critical limits

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
