Struggling with high operation cost, the Indian Railways has come up with a unique idea to increase its revenue by promoting movies, art, culture, sports or even television shows. The railways have decided to allow trains to be booked for promotional activities under a new scheme called "Promotion on Wheels", under which special trains will be made available for promotion.

According to Railway Ministry, the makers of Akshay Kumar-starrer 'Housefull 4' have already booked a train for the film's promotion. The first special "Promotion on Wheels" train with eight coaches by the Indian Rail Catering and Tourism Corporation (IRCTC) and the Western Railway, in coordination with the "Housefull 4" team, carrying celebrities and media persons, will leave Mumbai Central on Wednesday and reach New Delhi on Thursday.
