Thanks ЁЯЩПЁЯЩП. The first train to skip Katni was Ganga Kaveri Exp. back in 1977. In fact, it was also the first superfast train in the ET-ALD section. 12165/66 Ratnagiri was the 2nd train to skip Katni (after it got upgraded to superfast). But the first train not to have a commercial halt at Satna was the LTT-Patna superfast exp. I remember my trip on this in 2000. I was looking forward to a Satna skip but was rather disappointed that it had a tech halt there - for crew change.
