The trains running along the suburban lines offer frequent service but their doors don't close even during motion. Hang on tight or you will be among the scores that die each day riding the rails in this city.
The interiors are unappetizing. The windows have wire mesh so you can't escape in case of robbery or fire. You can't jump out back because there are metal railings in the way to cage you in like a prisoner.
The trains are subdivided into women's area, first class, and second class.
