Initially used to run from MAS to TVC as rajdhani and then extended to TVC via PGT - thats when Mani sir took this train from NZM to MAS but eventually when Konkan route opened it route got changed and had night dep from TVC to arrive around afternoon at NZM and then next day morning 10:55 AM dep from NZM to arrive TVC at 07:30 morning , now having worse time from NZM to TVC reaching TVC at 01:30 AM - Kerala SF and TVC raj time got changed at ZBTT to a worse TT.
Best...
more... time for this train would be to make this train leave around 13:30 PM from TVC to reach NZM at 06:00 AM and return should leave at 19:00 PM and arrive TVC at 13:30 PM
Also one new SR based TVC raj can be started that leaves TVC at 16:30 PM and arrive MAS at 06:00 AM and continue to reach NZM at 10:30 AM and return can leave at 15:45 PM to arrive TVC at third day morning 10:00 AM
