   I WAG-7
With the ever increasing freight traffic and the need for hauling heavier loads in 1 in 200 grade at increased balancing speeds, CLW went into for the design of an uprated version of WAG-5 locomotive with high capacity transformer, rectifier, traction motor, compressor and other matching associated equipments. These are six axles loco with axle and nose suspended drive. DC series motors, controlled by a tap changer are used in this locomotive. Indian Railway is going to achieve 7,00 million tonnes of traffic, WAG-7 is the main stay of loco. In the locomotive vehicle market WAG -7 is more economical option and one of the cheapest in the world.
 
5000 HP 25 KV AC WAG-7 Freight Electric Locomotive.
   Need :-
Due to advanced mechanical design especially those of bogies, the locomotive has low unsprung masses and is truly track friendly. Presently WAP-5 is the only passenger locomotive with fully suspended drive. Anti-collision posts give locomotive superior crash worthiness. The fleet of WAP-5 class locomotives is now being geared up for the proposed 150 kmph services
