In your opinion, which is the worst name change for a train and station respectively? For train, I'll go with the Netaji Mail. It's old name was proper considering it goes to Kalka(as the name suggests) and it has been known as the same for 150 years. There wasn't any political motivation either to change it's name considering the existing name had no connotations(contrast this with Mughalsarai Jn where the name change was done because the government had issues with the previous name; none of that issue with Kalka Mail).
