Oh, sure I ask you about a few nit picky details and you go right for
the "does it work" jugular vein. Just kidding. Actually, it doen't get
run that much, so I did some preliminary testing. I ran it backwards
over a point with five 8-wide coaches (no pictures of these yet) behind
it. It didn't seem to have a problem, but I have discovered that running
on the mostly flat and level basement floor does not necessarily mean
that there won't be problems running on the less than flat and level
tables at a layout.
On the other hand, I do know what you mean with respect to going
backwards with that kind of wheel set hanging off a motor. For example,
my SD40-2 will often pop its trailing wheelset off the track when
pushing its 8-wide load backwards (2 flat beds, 2 double stack container
cars, 3 box cars, 1 tanker, 1 hopper, and a caboose). Sometimes it
corrects itself when the train reverses to go forward, but if I push too
hard, it will derail.
I think that if I pushed the 4-4-0 steamer just as hard is the SD40-2
then I might start seeing the same problem. The one thing that helps the
tender is that the weight of the frame of the tender sits squarely on
the last wheelset. The last wheelset on the SD40-2 sits below some
plates that can be easily pushed out of the way. However, I don't think
that I'll have to worry about my 4-4-0 ever pushing a huge train. The it
simply does not produce the same tractive effort as the SD40-2. After
all, the SD40-2 weighs in at 1,000,000 mg (that is a kilogram to me and
you) and the tender doesn't weigh nearly that much.
By the way, I didn't think that you were trying to imply that I was the
boy in the men/boys women/girls thing. I just thought it was funny to
say that it would take a real man/woman to design the piston and
connecting rods since most "real" men and women think we are nuts :)

| Thanks! I hope you didn't think I meant that you are the "boy" in this analogy! I have been coping your work for years! :D Initally I had the cab further back but the MOC (LEGO selective compression etc... tight radius etc...) called for this (...) (19 years ago, 31-Dec-04, to lugnet.trains)
