The 12773 / 12774 Secunderabad–Shalimar AC Superfast Express is a Superfast AC Express train of the Indian Railways connecting Secunderabad (SC) to Kolkata Shalimar (SHM). It is handled by the South Central Railway zone (SCR). The train was announced in the 2012 Annual Railway Budget of India and its rake was rolled out in September 2012. The train stops at 14 stations en route, connecting major cities like Vijayawada, Visakhapatnam, Bhubaneswar and Kharagpur. The train runs weekly. The train was flagged off from Secunderabad on 28 May 2013^[1] at 11:00 am by Kotla Jayasurya Prakasha Reddy, the then Minister of State of Railways and Anjan Kumar Yadav, an MP from Secunderabad.^[2]

The locomotive links for this train have not been fixed yet but often the train is hauled by a Lallaguda-based WAP-7 or WAP-4 locomotive between Secunderabad and Visakhapatnam. Then, it is often seen with an Itarsi or Bhusawal-based WAG-5.

Overview

Since the train is fully air-conditioned, it has no unreserved coaches. It has 11 third AC, three second AC and one first class coaches. Along with two generator cars, it has 17 coaches in total. The train has no pantry car and offers no catering. The up train departs Secunderabad every Tuesday at 5:30 am and arrives at Shalimar every Wednesday at 9:05 am.^[3] The down train departs Shalimar every Wednesday at 4:05 pm and arrives at Secunderabad every Thursday at 7:00 pm.^[4]

The train has a total of 14 stops en route. The up train stops at Warangal, Rajahmundry, Samalkota, Visakhapatnam, Vizianagaram, Srikakulam, Berhampur, Khordha, Bhubaneshwar, Cuttack, Balasore, Kharagpur and Santragachi.Also there is demand that halt at Eluru railway station have to be provided. Unlike most trains, this train has two rake reversals, one at Vijayawada and one at Visakhapatnam. Albeit the LHB rake, the average speed of the train is only 60 km/h. The train's rake remains idle over weekends, which resulted in it being used during May–July 2013 to run a special AC express train between Secunderabad and Visakhapatnam, the route with the highest demand in Andhra Pradesh.^[5]

Technical

The train is equipped with LHB coach.^[6] They are considered to be "anti-telescopic", which means they do not get turned over, if the train derails or gets involved in a collision. These coaches are made of stainless steel and the interiors are made of aluminium which make them lighter as compared to conventional rakes.^[7] Each coach also has an "advanced pneumatic disc brake system" for efficient braking at higher speeds, "modular interiors" that integrate lighting into ceiling and luggage racks with wider windows.^[8] The improved suspension system of LHB coach ensures more riding comfort for the passengers compared to conventional rakes. The air conditioning system of the LHB coach is of higher capacity compared to the older rakes and is controlled by a microprocessor which is said to give passengers better comfort than the older coaches during summer and winter seasons. They are relatively quieter as each coach can produce a maximum noise level of 60 decibels while conventional coaches can produce 100 decibels. Each LHB coach costs between Rs 15 million to 20 million, whereas the power car which houses a generator costs about 30 million.^[9]^[10]
