but why do you want it to overtake mas mail? Mas mail has been running from years,same with shm tvc,but not as old as mail...about 5-6 years back,when mas mail was not under ser and not a superfast,shm tvc used to run from hwh and ran ahead of mas mail...now station changed...zones changed...train numbers changed...slot changed...passengers the same...mas mail being a daily superfast ought to go ahead anyways...
