Here's the funny thing about the handicapped compartments in Mumbai's local trains. You can only travel in them if you are permanently disabled (missing limbs, digits, organs; polio; cancer, etc.) and have a medical certificate from a railway official saying the same. This means that injured people (who don't fall in the permanently disabled category) are automatically excluded from travel in handicapped compartments and have to travel either first or general class, even if those cars are packed.
Sounds strange? Let's take it one step further. A lot of permanently disabled people aren't really in a position that makes it difficult for them to travel first or general. This means that a person who's broken or fractured a limb and who genuinely can't travel in a crowded train, can't make use of the handicapped car, but a person who just happened to be born with one toe less and who is otherwise completely healthy and normal and in no way physically unable to travel first or general, gets a lifetime handicapped pass. Unfair?
