Hiya Lyndsay!
Great to hear from you ... in answer to your question, I'm not exactly sure. I
only had it set up on a relatively small loop (exactly one dining-room-table in
size), so I'd suspect it will have many of the same problems when it gets too
far from the power source. Actually, the Hudson did have two motors in its
tender, though they were both pushing, whereas the Northern has one tender motor
pushing and a leading-truck motor pulling. Another advantage that goes to the
Northern is that I made it hollow, figuring it would have enough weight to
ensure good rubber-tire-to-track contact anyway (whereas I filled the Hudson).
Lifting them each, the Northern is still definitely heavier, but not by as much
as you might think. Maybe 20-30%?

Well, as Joe C. can attest to, the general shape was done within about a month
of starting - at that point, it looked like a boring long tube. Since then,
it's all been tinkering and experimentation with the greebling, with time off
for other projects and good weather :P There really was a tremendous amount of
carry-over from the Hudson, though - the piston rod system is a derivative of
the same design, as are the cylinders. If I had to put rough numbers on it, I'd
say that the amount of design effort that went into this engine was only about
50% of what went into the Hudson, even though it took about 3 times longer.
There weren't any design elements that held me up for more than a day or two -
it was usually motivation and competing draws on my time that stretched out the
contrsuction process.

Unfortunately, it's never Jeroen that is the choke-point in poster development!
He turns around designs so quickly, and they always look beautiful. Instead,
the hold-up is always me putting the .dat file together, and then responding to
his prompt e-mails in a timely fashion. I'll take it under advisement, but I
wouldn't expect a .dat file (and the resulting poster) for quite a while :)
Thanks for the comments and questions!
