## History

Howrah Mumbai Mail via Nagpur was started by Bengal Nagpur Railway as a through coach service on 1892, with trains changed at Nagpur on GIPR and Asansol on EIR. The through coach service was converted to a dedicated train after the completion of Tatanagar - Kharagpur - Howrah line and started on 1900 as the Howrah Bombay Mail via Nagpur, with train numbers 2 UP from Howrah to Victoria Terminus and 1 DN from Victoria Terminus to Howrah. It was a premium train service, with First Class and Second Class Reserved Carriages attached to the train, with Restaurant Car facility availed to these passengers. Intermediate and Third Class coaches were also attached to this train.
The number 2 DN / 1 UP remained till 1989 (with operation shifted to South Eastern Railway after bifurcation of Bengal Nagpur Railway in 1955) when Indian Railways shifted to a 4-digit numbering scheme. Train number was changed as 8002 UP for Howrah - Bombay Mail and 8001 DN for Bombay - Howrah Mail. After its conversion to a superfast train, train number was again changed as 2810 UP for Howrah - Mumbai CST Mail and 2809 DN for Mumbai CST - Howrah Mail.
After 2010, due to the 5-digit numbering scheme directive by Indian Railways, train numbers were changed to 12810 UP for Howrah - Mumbai Mail and 12809 DN for Mumbai CSMT - Howrah Mail.
