S-2 No. 765 in May 2013
Ron Shawley 
The C&O T-1 class with the 2-10-4 wheel arrangement was developed from the Erie 2-8-4. Lima reduced this again by one driving axle and thus created the class S of the NKP. In the years between 1934 and 1949, a total of 80 class S, S-1, S-2 and S-3 locomotives were built, which shone with exceptional performance and pulled fast freight trains. They produced around 4,500 hp and were designed for speeds of 70 mph. They were scrapped between 1957 and 1964. Today there are still six preserved. The best known is the 765, which runs fully booked special trips on a regular basis. The 779, which still exists today, was Lima's last steam locomotive built in 1949.
