Greetings to You as well! Yes! Future is bright for usage of 3 Phase Locos in IR (at least surely in CR/WR)! I am seeing more and more usage of 3 Phase Locos in/around CR/WR! Today's Pune-BGKT Exp was hauled by BRC WAP5 and tomorrow's Pune-Bhuj Exp will also mostly have BRC WAP5 (as one WAP5 is still available at Pune)! Tap Changer Technology will soon see the end and we will only see WAP5/7 and WAG9x locos being produced in future. Please don't worry! Best Wishes to You from my side! And may your all dreams related to 3-Phase Locos come true soon! Thanks!
