113 Coal

 · Bituminous: Bituminous coal is middle-rank coal between sub-bituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.

BNSF coal / ballast cars

 · My office is in La Grange, IL and I look out my window on the BNSF mainline - triple track between Chicago and Eola. Yesterday, cars numbered BNSF 912200-912250 rolled by - new from a manufacturer in an odd redish tone that were coal / ballast cars with what seemed to be solar panels attached to the side of the car and wires running out of the panels to a control box.

Difference in types of Ballast?

 · Historically, the ballast a railroad used was what was available on line, hence limestone in the south, ganite in the west, cinders or dirt anywhere, etc, as you note. As demands for a better track structure developed, many things changed. Ties got bigger, rail got heavier and the need for a good solid base to build it on got more critical.

coal dust for cinder ballast | Model Railroad Hobbyist ...

 · Real coal. Our club used real coal in the main yard, around the turntable area and on some of the industrial sidings. You can see where the rail has turned green, we constantly have to clean those yard tracks, and frequently find coal bits stuck to anything metal. The coal they used is magnetic and is a real pain.

Type of track ballast

 · Re: Type of track ballast. Postby Terry Bendall » Thu Feb 24, 2011 7:18 am. Being old fashioned we use granite ballast made for 2mm scale fixed with dilute PVA with a drop of washing up liquid in the glue. The ballast is only put down after all the track has been laid, wired up and tested.

Coal Trains Mean Coal Dust-Period

 · So much coal dust escapes from the open-top rail cars used for transporting coal that it can create safety problems for rail traffic. Coal dust deposits sometimes cause spontaneous fires, and in 2005, for example, coal dust that had accumulated in ballast, the layer of crushed rock that supports rail tracks, caused derailments.Given the coal export industry''s designs on the Northwest, it is ...
