Since this is supposed to be for any narrow gauge, Keystone Steam & Electric (1974) lists the PRR as having four (4) narrow gauge steam locomotives after 1906.
9661 ex-OR&W 5 4-6-0 scrapped 1929.
9663 ex-OR&W 7 2-6-0 scrapped 1928.
9684 ex-W&W 4 2-6-0 scrapped 1934.
9687 ex-W&W 7 2-6-0 scrapped 1934.
[the same reference states the PRR had a additional 20 narrow gauge locomotives in the 9600 series]
I'd like to find out more about the PRR narrow gauge lines. Can anyone recommend leads, books, photos, etc for me?
Thanks
Doug.
