WAP-7HS 30750 GZB shed High Speed Locomotive produced by CLW achieved speed of 180 kmph during statutory trials in RDT-LBN section of Kota Division on 12.8.2019. This WAP-7HS Locomotive is capable of pulling 24 coach train at 160 kmph as against the present maximum service speed of 140 kilometer per hour of WAP-7.

CLW produced this Locomotive in March 2019, within 6 months of assigning this work to CLW (Sept 2018) including design, simulations and production. This loco was dedicated to Nation by Honble MR Shri Piyush Goyal on 07.03.2019.

The complete design and development of locomotive have been done indigenously at CLW. The necessary simulation and modelling are carried out by CLW in-house. To enhance the speed of the locomotive, a weight reduction of about 14 tonnes have been carried out. The gear ratio changed from 3.6 (72:20) to 3.2 (70:22). The software modification has been carried out to optimize slip-slide control and tractive effort.
The new type of locomotive is expected to facilitate the operation of premium trains such as Rajdhani, Shatabdi and, Duronto at a higher speed.
