Who is the authority to allot locos to trains? What are the measurements to provide engines to trains?. I have verity of questions regarding this.
Ex. The Karnataka Express is actually a Bangalore bound train. But it never runs on SWR Locos. A CNB / BSL WAP4 is often seen hauling this train till ET, and from ET the famous WDM3A/3D twins bring the train to SBC.
1) What is the benefit that ET Shed or WCR getting by providing a loco from their shed to some other zone?
2)...
more... Which shed will bear the expenses that are incurred during the run of these huge machines?
3) Why dont the UBL or KJM locos pull the Karnataka express till ET?
4) Why cant the loco change take place at MMR? I have seen Karnataka Samparka Kranti getting loco changed from WDP4 to a WAP4.
