Weathering Engines; Steam and Diesel - TB Members

[Flash Blackman]

This thread is primarily a display of TB members' weathered engines. (http://www.trainboard.com/grapevine/showthread.php?t=95126) There is some discussion of types of materials used and some smaller discussion of techniques. It is a very good thread to give you some ideas of diesel model weathering. It is also very entertaining. It began as a diesel weathering thread, but now it also has a lot of steam engines, too.
