Gatimaan Express is not possible in existing timings and I don't think it is even required but Bhopal Shatbadi is already facing occupancy issues being a regular traveller seat are easily available in three digit number.
Coming to MTJ halt, that's true most of the trains are now skipping MTJ despite being a major halt and high boom of religious and cultural tourism, IR is simply ignoring it and focusing more on Delhi-Agra faster connectivity just by skipping MTJ which would make a difference of only 5-10 minutes. Pathetic Logic!
