In order to answer your question, Frank, I will post this picture of my VL BB on tubular O54 track. It sweeps the country side and looks terrible doing it, but I don't care. I never realized there were so many rules and obligations to owning this engine, I was just enjoying running it. It has not derailed, and I've run it a lot. I've really enjoyed running it and feel like it was money well spent. One of these days I'll build a bigger layout, but I'm enjoying it now, not some unforeseen time in the future. My intention posting this, which I was very reluctant to do, was to provide you with, hopefully, some helpful information. It is based on my personal experience of running this engine for a year now. After all, they are just toys, more sophisticated and expensive than what we grew up with, but still toys. Enjoy,
James
