India's rail system

It is said that to truly understand a culture, you have t spend time on the rails. With this in mind, I navigated my way through the Victoria Terminus to get a ticket for a 12 hour train ride southward to Goa. Upon my arrival, a man was being run through the terminal on a stretcher. He had apparently fallen off the train and was run over. I assume this as I cannot fathom another reason why his leg would have been bloodied and dissected. (apologies for those of you eating while reading). I was told that this happens quite frequently as people cram themselves on to the commuter trains. While I had hoped to experience the rails the way the locals do, I also decided it was probably best for me to get a reserved seat so that I wouldn't have to fight to stay on the train. After getting on three of the wrong lines, I finally got my ticket to Goa. 6am departure time. This is clearly not a vacation.
