briansilvermustang posted:The last and most unique of the F units, the FL9 was a custom fit for the unique commuter services in and out of Grand Central Terminal. Able to operate as a conventional diesel electric or pick up electricity from a third rail, the locomotives could operate safely in and out of the long tunnel into New York.
The FL9 had a unique 5 axle design and were longer than the typical F. They marked the end of F unit production in 1960 and were among the last in regular service in the US, securing their place in history and preservation.
Love the photos!
