MTH 20-2762-1 Union Pacific SD24 Diesel Engine w/Proto-Sound 2.0 #448 ProductID_11564592 Accurately reproduced side frames specificIn 1958, GM's Electro Motive Division took a great technological stride forward with the introduction of the turbocharged SD24. In turbocharged engines, exhaust gases are used to power a turbine that increases cylinder air pressure, thus effectively increasing horsepower. In fact, the 16 cylinder model 567 diesel that produced 1800 horsepower in the normally aspirated SD18 locomotive was upgraded to 2400 horsepower in the turbocharged SD24.
