How can I do good looking coal for a coal tender? The tender has an open face that points to the cab (so they can shovel the coal into the firebox) (20 years ago, 18-Dec-04, to lugnet.trains)

Hi All, I was totally inspired by a street of houses that I saw displayed at BrickFest in DC last summer (04) and wanted to build some for myself.
