One Point is very clear. Orthodox Trains are getting the 3-Phase Link. Still we have NOT seen any 3-Phase Link with any unorthodox One which is the "PREY OF THE TAP CHANGERS".
However, still IR follows it's conservative mindset regarding the usage of TAP CHANGERS. We have already seen 50 years domination of TAP CHANGERS in Indian Soil. If Luck favors in all respect surely relish those moments in future when 3-Phase will completely "OUST TAP CHANGERS AND ESTABLISH A STRONG POSITION IN IR". Eagerly waiting for that moment.
