MAQ-CLT-RU-BZA is 1265 Kms.
MAQ-MAO-UBL-BZA is 1180 kms. Amravati covers BZA-MAO in 19 hours @ 45 kmph. If speeded up, can cover in 17-18 hours. Plus MAO-MAQ is another 5 hours. Total 22-23 hours total distance can be covered via UBL.
Another alternate route MAQ-ASK-BAY-GTL-BZA. Total distance is just 1005 Kms, huge 260 Kms difference, when compared to via RU. Trains starting from MAQ should run via Karnataka, but there is no will to push further. If it is to benefit Kerala pax, it can terminate at convenient locations in Kerala....

By such routes in U shape , chances of getting trains connecting Karnataka towns is reduced. Hence, my red flag is retained.
