Re: air-conditioned coaches in old days...how did they do it?
OK, I think people kept themselves cool the same way the rich did before the advent of air-conditions.
Both my grandfathers worked in the Railway department of India and then Pak. I don't know a lot but I have heard about saloons in which the family would travel and which were resonably luxurious. Also apparently there were nice dining departments where good food could be had!
