Not disappointed at all. In fact, quite pleased to see the RTChallenge
still going on -- I've been out of touch for a while. I like the
RTChallenge concept selection and a quick visit shows some great images.

I'm not suggesting otherwise, but know from my own experience with
rounding objects that one must usually select a set of compromises and
constraints which affect the structure of his model as much as did the
manufacturing constraints of a real-life steam engine's construction
affect its structure.
It is, for me, interesting and often educational to see a similar model
constructed within a different set of constraints. So interesting, in
fact, that if I were to attempt to model a locomotive, I would likely
select an extremely limiting set of constraints in order to see how the
model developed within them.

Hey Christoph, you made my day! :-) I never knew about blind wheels and...
never noticed them of course. Thanks for the extensive info.

You bet I didn't either, before this! :-)
Had I not happened to come across this term by chance, I would have
considered it an oversight in the blueprints myself.
There's an /awful/ lot to learn about steam locomotives... you'd think
they're just boilers on wheels, with some steam cylinders? Well,
basically you're right... /very/ basically :-P
Did you know, for instance, how they get fresh water into the boiler
while "under steam"? I mean, they can't just open a lid and pour water
in, can they?
Even more astonishing is the fact that the device they use to accomplish
this has /zero/ moving parts. And to top it off, the device essentially
works by using the boiler's steam /pressure/ to have the fresh water
/sucked/ in.
Huh? Duh!
Perfectly black thermodynamics magic, as far as I'm concerned, but
Wikipedia claims it actually works:

Fascinating. Totally subjective of course, but I think steam engines are
more interesting than modern car engines. They have a raw and primitive
aura, and at the same time a simple efficiency.

I didn't know this but I think it's the same principle used
in some types of liquid atomizers, e.g. perfume bottles:

A block of concrete is more interesting than a modern car engine. At least
aesthetically :)

Somewhat similar, but not exactly the same principle.

I love the detail you've been creating here and I know (in some small way) the

I'm not a steam buff but for a project I and some friends are working on I
"modelled" a couple of steam locos and some rolling stock over the last year.
One of the main difficulties I found was that drawings are scarce and I had to
work from photos a lot. What this meant was that I didn't have the data to model
much of the substructure and chassis elements - and to be honest, I wasn't that
tempted to try!! You seem to have better drawings?? What loco is it?
I say "modelled" in quotes as my coding style is a tad shambolic and I tend
towards a sort of "lego" approach to things but at the start of this thread you
mentioned difficulties with complex cast iron items and I sort of glossed over
those by approximating with round boxes and so on. The worst part being the
slidey thing behind the main piston.
I was also be interested in your approach to the chimney and steam valve covers
- you used blobs there? I'm afraid I went traitorous and used jpatch for a mesh
object I (sort of) manipulated to fit. I also used jpatch for the firebox main
object.
Anyway - for your amusement I attach one of the loco renders.

Christoph is on vacation ATM and may not reply for a while. I like your
train, nice.
Bye the way, do you know this blueprint site?
