I would like to go to Pakistan to visit some of the Sikh Gurudwara's there, and I know that there are trains which go from India to Pakistan for which I require some more information about. I have some questions regarding the train between India and Pakistan, which I have listed below. 1. What is the process of the train when going from India? Do we need to change trains at the border? 2. Where does the train leave from which goes to Pakistan? 3. What is the name of the train which goes from India to Pakistan? 4. Do we require a visa to go Pakistan, if yes where do we obtain the visa from?
