The 12381 / 12382 Poorva Express is a Superfast train belonging to Eastern Railway zone that runs between Howrah Junction and New Delhi in India. It is currently being operated with 12381/12382 train numbers on a tri-weekly basis. History 
Before the introduction of Rajdhani Express in 1969, Indian Railway use to run a series of train called as Deluxe Express. One Deluxe Express use to run between Amristar and Bombay and other between Amritsar and Howrah. Both of these trains were fully Air Conditioned trains and the passengers were provided elegant services. Later on with the introduction of Howrah Rajdhani Express this train slowly lost its grandeur and popularity. Later on, in order to make this train more affordable to passengers further classes were added in this train, hence relegating it from fully air conditioned train to partial one. And later on with further standardization it was relegated to standard blue ICF coach. But though it lost its grandeur, but its popularity never ceased. Due to its high popularity, a separate service was started from New Delhi to Howrah via Patna on 1 August 1971. Poorva Express is the first train among the non-Rajdhani/Duronto class to be upgraded to LHB coach. It was upgraded to LHB coach on 30 April 2013. Service
