ALD, surely. Untill JBP line is diesel, thats the only place where u can see guys like Pune and KYN too! Others have just the boring electrics which are very much available in Delhi too.
But nothing beats MB in freight D-locos. In just the last 1 week I've captured IZN, JHS, UDL, ABR, LKO, SGUJ in the EMDs and UDL twins, KTE, GD etc in the ALCOs.
