The EMD SW1500 is a 1,500 hp (1,119 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Division from 1966 to 1974.[1] The SW1500 replaced the SW1200 in the EMD product line. Many railroads regularly used SW1500s for road freight service.[1]

It is similar in appearance to the EMD SW1000 model which has a different engine and has one exhaust stack while the SW1500 has two.[1][2]
