Trains 1. 02621 Chennai - New Delhi Tamilnadu Express 2. 02673 Chennai - Coimbatore Cheran Express 3. 02078 Vijayawada - Chennai Jan Shatabdi Express First Run of TN Express with LHB coaches : https://youtu.be/FM61rywHiMQ Journey by TN Express with LHB coaches : https://youtu.be/9VKHQZHr-EY The 12621 / 12622 Tamil Nadu Express is a superfast train of the Indian Railways. The train was first started on 7 August 1976 by then Prime Minister, Indira Gandhi. Introduced as a tri-weekly, it was the first State named train of the south. It runs between Chennai Central and New Delhi. It is considered as one of the fastest non-Rajdhani Express train. It runs with highly refurbished LHB Coaches from 22 November 2020. When first introduced, the train was numbered 121/122 and the train had 13 compartments and was hauled by a single WDM 2 locomotive. After the Madras to Vijayawada line was electrified, the train was hauled by a single WAM 4 Arakkonam Electric on that stretch, and a single WDM 2 from Vijayawada to New Delhi. When the Chennai - New Delhi line was partially electrified in the late 1980s, it had to change engines twice in the route, from WAM 4 to WDM 2 at Vijayawada and then from WDM 2 to WAM 4 at Itarsi Junction. When it was a non-daily train, it shared time slots with Andhra Pradesh Express and Kerala Express. The Tamil Nadu Express faced a problem with the engine when it had to haul 18+ coaches. Initially when it was introduced as Tri-Weekly, the train used to leave Madras Central around 07:10 am to arrive NDLS around next next day 12:50 pm. In return it used to leave NDLS around 07:00 am and reach MAS around next day 12:35 pm. But due to its aggressive schedule it was slowed down later. The reason is the train could not cover the terrains near Itarsi and was regularly late by 2–3 hours while on its way to New Delhi. 121/122 Madras-New Delhi Tamil Nadu Express are being run, as on experimental measure, with two engines from 29-1-79. It is too early to assess the full implications of this experiment. Based on the experience gained, it is intended to extend this feature to other trains/routes. Mr George Fernandes as Railway Minister, introduced the concept of twin engines and tried to fix the problem. Later the travel time was increased to 33 hours. The train was rescheduled to night later. The Special run of this train numbered 02621/02622 was upgraded with LHB rakes from 24 Nov 2020. The LHB rakes would eventually become permanent with the regular service. This train runs via Vijayawada, Warangal, Balharshah, Nagpur, Itarsi Junction, Bhopal Junction, Jhansi Junction, Gwalior, Agra Cantt and Hazrat Nizamuddin to reach New Delhi station. There is no stop between Vijayawada and Chennai. The train takes just 6 hours to reach Vijayawada from Chennai Central Railway Station and 6 hrs and 50 minutes to reach Chennai Central Railway Station from Vijayawada. The non-stop run of 431 km between Vijayawada and Chennai Central Railway Station is the second longest inter-halt journey for any train other than the Thiruvananthapuram Rajdhani Express or the Duronto Express, Kochuveli Dehradun Superfast Express, Kochuveli Amritsar Super Fast Express and Kerala Sampark Kranti Express (between Kota and Vadodara 528 km non-stop).
