PENNSYLVANIA RAILROAD GG1
ELECTRIC LOCOMOTIVE No.4800

STRASBURG PENNSYLVANIA
1934-1979

THE 4600-HORSEPOWER GG1 WAS PRIMARILY A PASSENGER LOCOMOTIVE, ROUTINELY OPERATING AT OVER 100-MPH, BUT WAS USED IN FREIGHT SERVICE AS WELL. CONCIEVED BY THE PENNSYLVANIA RAILROAD, AND WAS BUILT BY THE BALDWIN LOCOMOTIVE WORKS AND GENERAL ELECTRIC COMPANY, No.4800 LOGGED NEARLY 5 MILLION MILES IN ITS 45-YEAR LIFE. IT WAS THE PROTOTYPE FOR A 139-UNIT FLEET BUILT DURING A DECADE TO SERVE ON THE PRR'S ELECTRIFIED LINES, AND THE ONLY ONE WITH RIVITED BODY SHELL; THE REMAINDER WERE WELDED. THE STUNNING SUCCESS OF THE GG1 CLASS WAS DUE IN LARGE PART TO ITS FLEXIBLE SUSPENSION SYSTEM, WHICH PROVIDED FULL AND EQUAL TRACTION FOR ALL DRIVERS REGARDLESS OF TRACK CONDITION.
