As per my frequent observation the track is not fit for speedy motion. Also I have observed that soil has also lapsed under the tracks due to rains.
Earlier Kharar - New Morinda Stretch was also restricted to 45 kmph, but now NR/UMB has worked on it for an year and track is good now.
Hope they soon start restoration of NMDA - Sahnewal section. But it would take time at leadt 1.5 years from now.
