Southern Railway’s Royapuram shed WAP4 #22841 stands at Krishnarajapuram (KJM) Railway Station in Bangalore with the 16316 Trivandrum Kochuveli – Bangalore City daily Express on a gloomy morning, looking all sleek and fresh, after a scintillating run, reaching well before time! The paint has started flaking around its edges. The infamous “hanging bridge” can be seen in the background. The WAP4 is a 5350 hp AC powered electric locomotive which is a direct descendant of the legendary WAM4. It is the current workhorse of the Indian Railways hauling most long distance express trains.
