The results of an afternoon polishing the railcar can be seen in this shot. Railways do not preserve themselves. They require dedication and hard work to keep them going. Most of them are akin to painting the Forth Bridge. A lot of preserved railways run drive a steam train days. As far as I know none of them run polish a rail-bus courses.
Due to the efforts of my good friend Chris Ford, I now have somewhere to exercise my stock HO scale Norwegian railway models. A link to his blog is in the side panel. If you are interested, scroll down the list of topics and click on Svanda.
