Just Imagine, Chennai does NOT have direct connectivity to:
1. Saurastra & Kutch region in Gujarat(OKHA/PBR/Rajkot/Gandhidam) - Navjeevan Exp started way back in 70s continue to run packed but only till ADI
2....
more... Entire Konkan coast - Not even a weekly train in this route from Chennai, even though 4 daily trains run upto Mangalore, extending even one to Madgaon would run profitable and help passenger connectivity in this route
3. Inner Punjab(Amritsar/Ferozeppur) - Not even a weekly again. Worst even the MAS - Katra train is not restored
4. No dedicated train from Chennai to PNBE: Sanghamitra Exp started from MAS to Patna but was extended to SBC and since has reduced number in seat quota to Chennai....
5. In Rajasthan no train to Sri Ganganagar/Udaipur/Barmer
6. Uttarpradesh/Uttarakand:Western UP & UK not direct connectivity
7. Mahatrastra: No connectvity to cities like Ahmednagar/Latur/Nanded/Parli/HingoliWashim etc...
8. The cauvery Delta region does not have train connectivity to Delhi
9. CBE does not have proper connections to Delta except the single semmozhi exp; and Tiruchendur/Tutocorin
The list goes on and on.....
Only North east and east coast is adequately connected from Chennai
