Why to attach/ detach any loco link....what is the purpose? Are you going to run the train by attaching a loco? You only told sometime BSL P4, LGD P7, KYN WAG 9 , etc locos run this train ...in IR locos are attached as per availabilities no permanent loco all the year 365 days.....then why add any loco.....any shed loco can be added as per availabilities
My question is what is the purpose of attaching a loco in forum ?
