In fact the entire track from AGC to BPL is kind of a mess.
- Plenty of all year round restrictions around Morena, including that weird upward grade with traction break on Chambal bridge.
- Post GWL, SWR on every alternate non halt station, so even fast ones like Gatimaan are forced to drop to 70-80 km/h and then spend the next minute or more accelerating back to 130.
...
more... - As you had mentioned, low speed curves abound between JHS and BPL.
- Agasod - Bina has enough intersections to necessitate slowdowns, but this should be a little better once the route is tripled.
