The original group of E44's consisted of 66 units built for the PRR between 1960 and 1963. Forty-four were class E44 in 1976 and numbered 4400-4437 and 4460-4465, while units 4438 to 4459 totaling 22, were class E44A having been rebuilt to 5,000 horsepower from the original 4,400 horsepower. All units had dual controls, and the rebuilt E44A's were a tad bit lighter than the original E44's, 188 tons versus 192 tons. All were retired by the end of 1981.
A pair of E44s head north through Chase MD on the Northeast Corridor. Ten years later, this would be the location of the famous "Ricky Gates" wreck.
