F9 - MagnumMacKivler/RLCPT2 GitHub Wiki
Former Erie Mining Company 4214 is now a part of the Nickel Plate Express. This was taken during the "FC&N: One Last Ride" extravaganza by Sam Combs.
The EMD F9 series was a 4 axle, streamlined freight locomotive offered by EMD. Similar to the GP9, the F9 utilized the updated 567C engine block that made an additional 250 horsepower compared to the previous F7 model. In total, 257 (101 cab A units and 156 cabless B units) were made, compared to the F7's 3856 locomotives made); this is likely from a majority of customers moving to the better visibility of the General Purpose hood locomotives instead of the cowled, streamliner F unit series to move freight.
While locomotives like the F18 and F20 were offered, none were physically made for any customers, making the F9 the last of the F-series locomotives made by EMD.
