I would like to add that we model railroaders are helped directly every day by many, many train crews. If all those crews weren't out there running real trains moving coal&oil we wouldn't be running our miniature railroads in our safe places. Until Renewables take over completely and we are using the power of the Sun directly electric power production is gonna' need help from long-stored Sunshine (coal, oil and gas).
Now that the Hoosac Tunnel is reopened there are strings of Propane tank cars going up our valley every day headed for Boston to heat people's homes and cook their food.
The list is quite long. But everyone here already knows this stuff.
