NCJ CBE passenger converted to express should be a night train via Palani instead of daytime via Erode. CBE Dindigul line is totally underutilized.
For NCJ Erode daytime travel, weekly 4 days NCJ CSMT can be used.
In this daytime slot, new train from NCJ to TPTY Via MDU DG KRR NMKL SA KPD can be run. All trains from south TN to TPTY are in zig Zag route now.
