* With large number of electrification projects already kick started by IR, it is clear that electrification of almost 100% BG routes is inevitable. It will happen may be in next 6 yrs or 12 years.
* Success of Diesel-Electric dual loco depends on many factors like:
(1) Technical performance of loco-operational flexibility, reliability, maintenance, weight, etc.
(2) Cost of Diesel-Electric loco...
more... as compared to Eloco with respect to manufacture as well as maintenance.
* best use of dual loco should be normal operation on electric traction and using diesel traction during acceleration or during the power failure or fault in power supply.
