We're not ignoring your railroad. Since you haven't posted any pics of anything, it's, well, it's a bit dry, honestly. I'd like to see pics of what you have, too. I have a few of the battery operated trains, though for now they're all boxed up, with one exception...
Don't feel too bad, I have a few others that are in working order. I purchased this one years ago from Property Control, where WDW sends damaged merchandise to be sold on the cheap. I bought it to add rolling stock to my inventory. The engine didn't work, so I decided to take it apart: a) to see how everything was put together and how the smoke unit worked (who knew it amounted to a mini punching bag to propel air up the tube to blow smoke?); b) to see if I could find out why it didn't work; c) to repair/kitbash it to represent another WDW engine. As you can see, I have yet to get it working and put back together. It's been in pieces for about six years now. Maybe someday. Incidentally, aren't New Bright and Scientific just different names/divisions for the same company? Their products, by and large are identical and interchangeable.
