Here it is, in p.b.i, after getting lost in p.u.p for a few seconds...!
My first car. M-K-T Missouri-Kansas-Texas line "The Katy serves the
Southwest". And by chance same region as the Kansas City Southern
locomotive so my train'll look somewhat intelligent. :)
Ignore that the car is hovering over the reflective plane... ;)
This was nothing compared to the locomotive! Obviously lots and lots of
loops to place rivets etc. Hmm, now I can make a boring train with one
car tiled to the horizon. I could just create new image_maps and have a
two boxcar train, but my non-functioning scanner means eyeballing
everything by hand on top of a plan render again. At least my Santa Fe
car doesn't have any script on it, so no more b-spline polygons with 80
points...
There is a minor texture alignment problem. You wouldn't be able to tell
except where it says "BLT 1-92 LIONEL" by the door, that should be
entirely within the recessed portion. The other half lines up and is
basically the same image, but it turns out that to rotate one side to
match the other side the axis is not right in the middle, it's at 0.3*x
(out of a car length of 24 units). Gets hard for me to keep 2996 lines
of code organized.
Anyone care to make me a track landscape? j/k ;)

I already thought several times of such a thing, there are some things
that need work:
- fast solution for the track itself. Since only parts are visible in
detail anyway, the prism/lathe solution is quite ineffective. Some mesh
would probably be better.
- building the path is quite problematic too since it would involve
changing the shape of the terrain either with csg operations or direct
manipulation
Anyway it would be quite difficult to get it as realistic as your wagon.

Seems real to me.
I would like to add some more comments but I don't know the right expressions
for the parts so I'll just say that I noticed the bit with the wheels and like
the springs in them.

Actually, that would seem fun.
I didn't play with trains a lot, but I did (do) like all the computergames with
trains in them.

Other problem is placing the cars on the track. Lots of mathematics, finding
where a circle with radius of the distance between the two sets of wheels
intersects the track. That's the easy part, then there's aligning the
wheels; if the wheels are perfectly aligned with the track, the couplers
won't necessarily line up, but making each coupled set of wheels rigid
wouldn't look right either...

thanks. I called 'em object { BC_Wheels }. ;)
The suspension is just stacked torii, the cheap way of imitating a helix. My other
boxcar has a different wheel assembly, but I can just reuse this one, nobody'll know.
It's a K-Line Santa Fe, and it has a real working suspension, unlike the Lionel. :)

I think it'd be best to do most of that outside of POV. At any rate it's work for some
other day...

I wish I had the patience to code this, well done look forward to the
finished result.

I could say the same about a lot of your work...

Thanks, but school's back in session after winter break now... check back
during spring break. hehe
Hmm, World Literature paper, ooh, fun! Ooh ooh! SL History exam paper!
Why the hell did I sign up for the SL History exam? It's worthless!
Perhaps I should blow it off. Ooh ooh! Sure wish I was in physics 'stead
of chem this year. Oh well. Time to go do my calculus portfolio, or maybe
my "lit log".
