This is probably the last instalment of MG routes from Delhi to the major cities in South India. Trivandrum came on BG in late 1975, so this time we imagine a journey in 1970. One could also imagine a link express from Quilon to Ernakulam.
This comes to 3249 km, which is just over 2000 miles. Probably it would take a week.
In 1970, TVC was indeed the southern-most station in India as its latitude was less than that of Tiruchendur, which remained on MG until 2000 or later.
We have covered various long metre gauge journeys which were possible in 1976, such as Delhi-Madras, Madras-Bangalore, Delhi-Bangalore etc. There was also East-West route from Okha (or Varvala) to Lekhapani. These were the furthest west and east points of IR at that time.
Now we come to the route connecting the northern extreme and southern extreme points of metre gauge.
At that time the northern extreme of IR was Jammu Tawi on BG. On MG it was Kot Kapura:
For a short time in the 19th century MG extended from Kot Kapura to Ferozepur (Cantt?) making it the northern extreme of MG at that time.
In the south, there was Tiruchendur, on a branch line from Tirunelveli was the southern extreme of metre gauge. Earlier Trivandrum Central had this honour, although it was converted to BG by 1975.
This North-South MG route was touched upon here:
Anyway, the full route including important stations and distances is given below. Spellings of place names are those given in timetables of 1976. The distances between Khandwa and Hingoli had a separate “chargeable distance”, although we have used actual distances here.
As of 2022, a large proportion of this route is now broad gauge, while the remaining metre gauge counts off its last days.
This route passes through NR, WR,CR, SCR and SR as they were at that time.
It passes through the states of PB, HR, RJ, MP, MH, AP, TN (besides the future TG).
