after completion of doubling work between MS - MDU route....surely they ll give P7...some tyms if WAP-7 fails in enroute it will be very tough to rectify ..whereas WAP4 is not like that we can trouble shooting is easy...in WAP-7 no trouble shooting just we need to isolate the MCB switches thats all.....so if WAP7 fails big trouble for LP and ALP's and respective officers...
