Re: Less popular on the narrow gauge...?

"Other than the D&RGW and Uintah, did any U.S. narrow gauge railroads order new non-geared steam locomotives after 1920?"

Table in Hilton's tome shows the following built after 1920:

1923 Alco... 10 units (D&RGW K-28)
Vulcan... 2 "

1924 Baldwin... 1 "

1925 Baldwin...10 " (D&RGW K-36)
Alco... 2 "

1926 Baldwin... 1 "
Alco... 2 "

1928 Baldwin... 2 " (Uintah "Mallets"?)
Burnham...10 " (D&RGW K-37) (actually built 1928-30)

1929 Baldwin... 1 "

1938 Baldwin... 1 "

1939 Baldwin... 1 "

1943 Baldwin... 8 " (were these for WP&Y?)

1947 Baldwin... 2 " (WP&Y #72-73)

A total of 53 were built for common carrier use post-1920. Of course this does not include locomotives for industrial use. Heisler built their last narrow gauge locomotive about 1932 - a 42 in. gauge unit for a coal mine in PA. I do not have figures for Lima shays or for Climax which folded in 1928. Porter built industrial locomotives until 1951, some of which were undoubtedly ng.
