Sean - just want to say, _fantastic_ engine. You can't even tell it's Lego
from the thumbnails! The working linkages on a flexible wheelbase are just
amazing. But why a German steam train? Did you just have a lot of black
bricks around? What's wrong with a nice colourful British one? :)
How long did that take, btw? I don't mean hours. How many days / weeks
have you been thinking and working on that? The level of detail is amazing.
Using those model team wheel hubs will mean that the train will stay on a
simple loop, but won't take points (OK, 'switches' in the US) or crossings.
The larger ring of the hub can't get past the alignment strips just inside
the rails on these track pieces. They'll ride up, and de-rail.
The wheel <part:2695> consists of a narrow hub with a ridge to hold the tyre
in place, a flange (with 6 technic holes) to widen it, then a 1-stud deep
thin-walled ring to support the rest of the tyre.
I've cut away the ridge and this ring on a few of these wheels I've picked
up from old second-hand purchases, to just leave the smooth inner hub and
the flange - they make fantastic train wheels like this. I'll post some
pictures soon of the process.
I know it's bad form to modify Lego parts, but how else are we supposed to
get hold of driving wheels?
I've tried to get hold of a load of black ones from Lego Customer Services
for my trains, but they'll only sell me white ones. Single black ones have
appeared in a few non-technic sets as decoration, such as the <set:6497>
Twisted Time Train (on the chimney), and the <set:5928> Bi-Wing Baron
(rotary engine casing).
If anyone has a load of black ones to trade, or has a source (6 or more),
I'm interested btw.
Another problem you might have with points is flexibility. Just putting
pivot points in the wheelbase won't handle points. You could just have
pivots between individual axles, but this is unstable in a long train. What
you need are fishplates (a plate pinned at each end) between trucks of four
wheels each to allow a little snaking movement too, for when you go from
curve to straight, or curve one way then the other.

| (...) Thanks, Jason. I picked the German steam train to fit in with the motif of my other models, primarily, as I tend to lean towards utilitarian workhorse designs. Political ramifications aside, the German industrial boom of the 1930s produced (...) (23 years ago, 27-Mar-01, to lugnet.trains, lugnet.build)
