Riding trains in Pakistan is a riot. Check out this picture showing Pakistani Sunni Muslims devotees returning back to their homes on a packed train after attending an annual religious congregation in Multan, Pakistan.
Pakistan Railways carries 65 million passengers annually and daily operates 228 mail, express and passenger trains. The number of passengers carried daily is thus about 178,000.
You can't get more efficiency in terms of utilization then what they have done with this train. Wonder if all of them have bought tickets?
