The route maps of the Indian Railways have undergone major changes since 1975.Construction of new lines, large-scale gauge conversion and the upgrading of many hitherto minor routes have all taken place.
Here we start with the All-India Time Table of November 1975 and see which lines have vanished from the passenger timetable.
The timetable was arranged in alphabetical order, so we start with the Central Railway as it then was. Many changes occurred since then, with part of the South Central Railway going back to CR in the late 70s, and CR itself losing substantial parts to the new North Central and West Central zones in the early 2000s.
Note that we are here using scans of scans, so some of the old timetables may not be as legible as we would wish.
T 17: Majri-Rajur: The section between Majri and Wani is now part of the longer route from Majri to Pimpalkuti, Adilabad and beyond. Rajur still has goods services but not passenger services.
T19: Tadali-Ghugus: No passenger services, still has goods services.
T22, 22A: Note the local trains between Pune and Dehu Road Depot, which is on a branch from Dehu Road. Passenger trains on this branch stopped long ago.
Note the footnote (for Contractor’s Labour, Military Department’s Workmen and Staff).
The future of some narrow gauge lines such as Murtazapur-Achalpur are uncertain at the moment.
I also added a major realignment where a number of stations went off the railway map. The Harsud realignment was caused by the reservoir of the large Indira Sagar dam. The Khandwa-Itarsi section, while not exactly being on the Golden Quadrilateral, does have heavy long-distance traffic from the Mumbai area to northern and eastern India.
Note the section after Khandwa here:
And compare it with this map (from the Great Indian Railway Atlas, 2015):
Note that the existing alignment up to Bir is still used for local passenger trains. This realignment has increased the route by 6 km.
Next comes ER (including suburban services).
