History of 84/ 114 : This began as DLI - LKO Express. Was extended to BSB on 4 days via Faizabad (84) and 3 days via Sultanpur (114). Then began a series of extensions/ curtailments - Danapur, Malda Town, Mathura via Tundla (cancelled now), Bhiwani (cancelled now). For some time the train used to split at Tundla with one part going to Mathura. It was known as the Ganga Yamuna Express in those days.

Just 2 years prior to this (1975), 156 Tinsukia Mail used to start from Delhi Jn. at 19.20 on Tues, Thu, Sat, and go via Patna - Kiul. 164 Tinsukia Mail used to leave Delhi Jn. at the same time on Mon, Fri and go via Gaya - Kiul.

Samar, Yes, the Lal Quila Exp is the present avataar of 11/12 Delhi - Howrah Express. 2 nights from DLI to HWH.

The Assam mail resembles the present NE express. There is no train close to Tinsukia mail though. What about this 11/12 DLI-HWH express, is the new Avtaar of it Lal Quila?
