Many mistakes are there in Tollywood, Bollywood movies when it comes to railways.... Sometimes during fight sessions, they show entirely different.
If u have watched Simha of Balakrishna, there is a fight after the interval. 3-4 trains cross in 5mins... that was hilarious one.... The list is long.. Perhaps they need to do some research while making train movies..
Not all movie can b like Unstoppable..
