Also, what is a tipple (sp?)?
And what type coal did they use to fuel steam engines? Whatever was most available?
A lot of mines and breakers are disappearing, but the anthracite coal supply is still there. Estimates range from 200-800 years worth at the current rate of consumption, so it will be around long after oil and gas are gone.
A tipple is the thing that loads rail cars with coal.
Mostly bituminous, but obviously if anthracite would be easier to get it would be used.
