But there is not change in timings or speed after emd is given so whats the use ok if this train is having more than 20 coaches then emd is required for 14 coaches alco is more than enough. First of all kjm is giving away some of its emds to other sheds to accommodate electric locos. Erode diesel shed also have less number of wdp4d if there are surplus locos they can provide emds to each and every diesel haulud train.
