Not sure to have patronage between ERS to CHTS alone. Something on suburban model from AFK, TRTR is needed. I would say even connecting TCR is needed which will bring revenue. They can also think to extend train that earlier ended at ERS (of course those with Diesel engine).
Let us see how it goes; going my historical data, the chances are high that these DEMU coach will go back to Chennai after a month (save this to review later)
