The New Haven EP-5 was a double-ended mercury arc rectifier electric locomotive built in 1955 by General Electric, for the New York, New Haven and Hartford Railroad. It was built to haul passenger trains between Grand Central Terminal or Penn Station, New York City and New Haven, Connecticut.
The EP-5s were the first AC passenger electric locomotives to use rectifiers to convert alternating current from overhead wires to direct current (DC) for the traction motors. They also collected DC from the third rail used by the New York Central, whose tracks the New Haven used to reach Grand Central Terminal (GCT).
All of the class were equipped with the Pennsylvania Railroad's cab signal system needed to operate into Penn Station; Washington, D.C.-Boston through trains over the Hell Gate Bridge, plus the Montrealer/Washingtonian, were their main assignment throughout their New Haven careers.
The units were known as "Jets" due to the roaring sound made by their main blowers; an example of this characteristic was inadvertently preserved for posterity in a scene shot at Grand Central Terminal, the very first moments of the movie The Man in the Gray Flannel Suit.
Joey, Joey, Joey
Joey, Joey, Joe
You've been too long in one place
And it's time to go, time to go!
Joey, Joey, Joey
Joey, traveled on
You've been too long in one town
And the harvest time's come and gone.
That's what the wind sings to me
When the bunk I've bunkin' in
Gets to feelin' too soft and cozy,
When the grub they're been cookin' me
Gets to tastin' too good,
When I've had all I want
Of the ladies in the neighborhood.
She sings:
Joey, Joey, Joey
Joey, Joey, Joe
You've been too long in one place
And it's time to go, time to go!
