Notes: The FT stood for Fourteen Hundred Horsepower (rounded up from 1350) and T for twin, because they were sold as semi-permanently coupled A-B or A-B-A sets to get around railroad union regulations. The B units had no batteries as well, to make them electrically dependent on the A units for starting to further emphasize this point to the regulators. Some railroads ordered theirs with couplers for extra flexibility.

FL9A (New Haven Class EDER-5)

Produced: October 1956 to November 1960
Production: 60
Horsepower: 1,750 hp EMD 16-567C Two Stroke Diesel (first 30), 1,800 hp EMD 16-567D1 (last 30)
Weight: 266,400 lb
Length: 58 ft over couplers
Top Speed: 89 MPH
Tractive Effort: 58,000 lbf

Notes: Built for the New Haven railroad specifically to operate on third rail mode within tunnels and Grand Central Terminal in NYC. The first thirty were the EDER-5 class, the last thirty were the EDER-5a class. The two major differences between the FL9A and a standard F9A were that the FL9A was even longer than the FP9A to provide room for the extra equipment required for third rail mode and had a six-wheel #2 truck.
