When will this become available?  Price?

Are the 2-8-0 engines physically bigger/longer than the 4-4-0?  What radius do they need?

I purchased the 2 truck Shay, Climax and 4-4-0 Spectrum a few years back.  I cannot find the manuals for disassemble now that I want to add sound and Locolink and I no longer have a working VCR machine (everything is DVD).  Are the manuals available in PDF format and video available for download?

I recently had my Shay on my desk just looking at something and after I took it back I found a small all bearing sitting on my desk.  I have no idea where it came from and would find it hard to believe it was there before.  It is smaller than a BB and silver.  Has some residual oil/grease as it sticks to my tweezers.  Can anyone tell me if that could have possible come from the Shay and where to look.  Thanks in advance. 

I now have 2 dead Christmas gandy dancers and the regular moves but the handle does not move up and down any more.  Are parts still available?  I know you can repair them, but the $50 cost plus shipping I might as well buy another.  They don't seem to last.

The other day, I notices a missing piece on the top of the coal tender.  It is a small water valve I guess.  There is one on the exact opposite side that is there.  It has like a little handle on it.  The missing one is on the right side of the unit.  How do I get a replacement?

I bought both the Climax and Shay a number of years ago and they came with a VHS tape for maintenance.  We no longer have a tape player.  Are they available anywhere in video format?
