Out Arizona Way

[ezdays]

Back in the day when the Florida East Coast RR was still hauling people and tank loads of water to the Florida Keys both were hauled in cars that were black with white lettering. And this was before there was air conditioning! I figured the water in the tank cars had to be near the boiling point!

That's probably because black paint is cheaper and easier to apply than white. It was also inconsiderate to those that use that water. Most water heated that way winds up with a peculiar taste. I've left bottles in the car and it gets hot enough to scald. Cool it down and it tastes like the container.... I would assume that a tank car full of water would do the same.
