| Abstract | Measurements of the noise from a General Electric C36-7 diesel electric locomotive were performed with the locomotive stationary and attached to a load cell during powered and unpowered pass-by tests. The pass-by tests demonstrated that wheel/rail noise contributes little to both interior and wayside noise when the locomotive is operating under load at throttle 8. Stationary tests examined the directivity of noise around the locomotive and the contribution of the major sources to the noise signature. At throttle 8, under load and at idle, the exhaust and radiator cooling fan were the primary sources. At throttle 8, unloaded, the radiator cooling fan exhaust and equipment blower dominated the noise. |
