please wait...Translate to EnglishMumbai Kalyan is a suburban area that falls under MRVC, and the train tracks here are very close together, making it difficult to increase the speed. Additionally, there are limitations on available land.
Kalyan Kasara is a route with lots of curves, so trains can only go up to 105 kmph in this section. A third line is planned to be built here to increase capacity.
Now that the route from Igatpuri to Nagpur has been upgraded, we can expect the premium trains to speed up soon.
