Editing EMD F-unit (section)

==Options==
There were several options that could be specified by customers for the F-units, such as type and mounting location of [[train horn|horns]] and [[bell]]s.

===Dynamic brakes===
[[Dynamic brake]]s were an option on F units ordered by railroads operating in mountainous terrain and with steep grades.

===Passenger or freight pilot===
Either a passenger or freight style [[pilot (locomotive attachment)|pilot]] could be ordered. The passenger pilot, similar to that standard on E-units, slopes smoothly down from the bottom of the nose, making a single slope all the way down from the headlight. The coupler is retractable with concealing doors. The result is a very attractive appearance that enhanced the impression of a powerful and speedy machine.

The freight pilot curves inward a little way below the bottom of the nose before sloping out again, to give more clearance to the coupler and hoses. The coupler is fixed and protrudes through a rectangular opening in the pilot.
