Have you ever wandered why there is a big "X" drawn at the last coach of Indian Trains?

Indian rail coaches often have a lot of symbols and letters on them that we don’t understand. One of them is the large ‘X’ that is seen on the last coach of a train. A lot of us have different ideas about what the ‘X’ symbol means. The Railway Ministry took to Twitter to explain the logic behind the symbol and people finally got their answer.

Taking to Twitter, the Railway Ministry tweeted, “The letter ‘X’ on the last coach of the train denotes that the train has passed without any coaches being left behind.” The symbol signifies that all coaches of a train have passed without any coach being detached. It serves as a confirmation for the railway officials. The ‘X’ is painted on the last coach of a train in yellow and it can be seen on any passenger-carrying train and on freight trains.

While we dig a little further we came across an article which says something else. It says that the X on the last coach of a train is for safety reasons. The X symbolizes the fact that that coach is the last one in the train, so the passengers will know that they shouldn't try to approach the track any further ahead of that coach. It's often accompanied by a warning light and an audio message to make sure that everyone is aware that they shouldn't approach the track beyond that coach.
