Very slow speed from TCR to PGT and PGT to CBE. TCR to PGT can be done in 1 hour and so PGT to CBE in 1 hour. Moving via A line could also save some time in PGT to CBE section.

Not sure if it do up and down in same day with single rake considering speed restriction in the area in case if made daily

One way to do it is if CBE BNC VB starts at 06:30 AM and arrive BNC at 12:55 PM , the same train can leave to ERS via JTJ bypass at 13:45 PM and arrive ERS at 22:15 PM.

The train leaving ERS at 06:30 AM can arrive BNC at 15:05 PM and can leave as CBE VB at 16:30 PM and arrive CBE at 22:55 PM

With PM at CBE

Best option is to make CBE VB via JTJ bypass with stop at tiruppur and Uday via Hosur Dharmapuri after testing, That would be a faster speed for VB and save lot of time.
