hi friends I am thankful to the Railway authorities for introducing a system where one can complain from a running train and doubly grateful that they have acknowledged the complaint and attended. The Railway Number to which you can SMS is 8121281212. All you need to do is mention the train number and bogie number and the type of complaint e.g: A/C not working / Toilet no water etc . Please pass on this message to your friends and it may help some one in need including you.
