Bill~,
Thanks for the generous compliment. I will finish this model soon (I'm working hard to get to it again).
Thanx Thom...

Thom, Not being the sharpest cookie in the box, I only recently rediscovered where the "subforums" are on the new format and just saw all the work you've done on th C-855a.
Wow! both for operating ability and looks!!
Now that I found this I'll follow along as you finish weathering and do the b unit.

Cody~,
Thank you! I can't wait to finish this one as soon as I can carve out some more time. It seems life is like a roll of toilet paper~ the more you get into it, the faster it seems to go. Where does the time go anyway?
Thanx Thom...

Double wow! Outstanding work!

Thank you, Philip, I'm glad you liked it.
Thanx Thom...

Beautiful loco!
Philip

Joe,
You're welcome. Glad I could entertain a bit here. I'll post more on it when I finish the weathering.
Thanx Thom...

excellent work ! thanks for sharing

Special K~,
And now you know why I have 855 in my forum name.
Thanx Thom...

Nice work, C-855 always a favorite of mine.

Thank you DD (desertdrover). While this was a much tougher build than I originally thought, it turned out well (even tho I'm not finished just yet)(I gots lots of weathering when time allows).
Thanx Thom...

Fantastic workmanship on this locomotive Tom. I can only agree with all before me. Great Job! Getting those baby's to navigate a 22" radius is a feat in itself.

Thank you Rick, George, Jerry & Bern,

Bernie, I figured you and a couple others would pick up on that tower connection right away! When looking at both span bolster frame work you'll notice the added back material. I originally tried the towers apart rather than the finished together. That proved to be restricting in my turning radius' (I think it had a hard time going through #9-10 switches). So I turned the two outer towers inward together and they did much better.

That produced another problem (the almost no space between worm shafts). So the original models had the springs on their worm shafts so I stole their design and used it on mine.

The next (the main) requirement was always to have this model run smooth and quiet (and it does very well). I make all my engines run through the minimum #4.5 turnouts and 22" radius curves (although this will go thru a #4/18" 9/10 times) I don't build them for that and don't guarantee it.

I have a few other Ideas on the "B" unit when I get around it. Worst case, I'll just copy what I did on the "A" unit then.

WOW Tom, I'm impressed with that step by step procedure.

Interesting coupling between the two truck towers. looks like a spring for flex when running around curves. I guess it must be smooth since I didn't see any complaints about noise or vibration.

Again great job on that up grade. It's getting me to want to redo a couple of Hobbytown projects I've got waiting in the wings.

Beautiful! That's impressive work, Tom.
