INDIAN RAILWAYS Brief description of the loco Driver's Manual for WAG9 2. BRIEF DESCRIPTION OF THE LOCO: The WAG-9 &9H is a high-speed main line locomotive for hauling FREIGHT trains and WAP-7 is a high-speed main line locomotive for hauling PASSENGER trains. This locomotive is a double-ended design, which means that there are a driver’s cab and coupling elements at both ends of the loco. 2.1 Mechanical Features: The three axles, three motor Co-Co bogie assemblies, is one of the major parts of the locomotive. Two bogie assemblies support the entire weight of the locomotive and provide a means for transmission of the tractive effort to the rails. The bogies are designed to withstand the stresses and vibrations resulting from normal rolling stock applications. An important function of the bogie is to absorb and isolate shock caused by variations in the trackbed. The suspension systems minimize the transmission of these shocks to the locomotive under frame. The traction motors are suspended in the bogie frame and on the individual axis. The motors transmit their energy to the driving axles through a gearbox mounted on the driving axle. The force from the driving axles is transmitted to the contact point between the wheel tread and the rail. Traction force is, in turn, transmitted through the axle journal boxes and guide rods to the bogie frame. The push-pull link rod, connected between the bogie transom and car under frame, transmits the tractive forces to the car body. The WAG-9/9H is equipped with the following pneumatic braking systems: automatic train brake, direct loco brake, parking brake, and anti-spin brake. As with the tractive effort, braking effort is transmitted to the bogie frame by the axle journal boxes and guide rods and from the bogie frame to the locomotive by the traction rods. Isolation and absorption of shock loads and vibration is performed by the primary and secondary suspension. Movement between the car body and bogie is smoothly controlled by the primary and secondary suspension. Although the springs permit free movement in any direction, lateral buffers and dampers limit the amount and rate of lateral movement. Rebound limit chains and vertical dampers limit the amount and rate of the vertical rebound of the locomotive car body. Yaw (longitudinal) dampers control the car body pitch rate. Guide rods control the fore and aft movement between the axles and the bogie frame, while the link rod controls the fore and aft movement between the bogies and the locomotive car body.
