Electric locos provide great acceleration but nothing can be matched to a d-loco. Really missing those days when TPJ-CAPE was a diesel kingdom. Vaigai with d-loco between MDU and TPJ in the morning hours is simply awesome. Once when I went in Pandian from Chennai Egmore to Madurai (In TPJ-CAPE line's diesel era) , I woke up at TPJ and checked whether that the d-loco was attatched.
It was not. The ED WAP-4 which led us till Tiruchirapalli continued. I felt disappointed. But at last to my relief An EMD replaced the WAP 4 at dindugul. Finally I got happy :)
