Why do they make trains so hot?

As the days are getting shorter, and the temperature drops I have cause to wonder about the heating system in trains.

Imagine, if you will, a cold winter’s day.  It’s only 7 a.m. and it’s still dark.  The sky is clear, the frost is glistening in the lights of the station.  It’s cold.  So all the people waiting for the train are wearing coats, perhaps gloves, maybe even woolly hats.  And why are they wearing this stuff – because it’s cold!

The train arrives, the doors open and all the passengers pile onto the train – which is heated to furnace temperatures, and all the people who have big heavy coats on are now boiling hot.  By the time the train has gone two stations, they’re dripping with sweat, and they can do nothing about it because they’re packed in like sardines.  By the time they get to the end of the line, they’ve lost 2 pounds in weight, and feeling thoroughly miserable, and they smell.

If the heating had not been on, no-one would be cold, no-one would be sweaty, no-one would smell, BECAUSE THEY”RE DRESSED FOR THE COLD.

Surely it’s not beyond the wit of man to get this right, and make our winter journey to work that little bit more pleasant????
