After seeing Larry's LDRAW rendition of the 2-wide train designed by Jorn
(http://www.brickshelf.com/cgi-bin/gallery.cgi?i=30198), I decided to try and
incorporate it into a "full-scale" train car.  The result was an 8-wide flatbed
with a small train running atop it:

There's also a 3.5 MB mpeg of it running, thanks to the kind video stylings of
Jaime:

It was a big hit ... there were many cries of "Look at the last car when that
train comes around again!" and the like.

Currently, the tension in the chains is a bit high, such that the motor starts
to get hot and jumpy after about 20 minutes of continuous operation.  I'm
figuring to either gear the whole thing down a bit, or add a spring-loaded
tensioner rather than use the standard technic hole spacing to relieve that
problem.

I've since been made aware of a similar mechanism on Daniel Siskind's
Brickmania Toy Werks ... no fair, his train looks fancier than mine! :P

Enjoy,
Shaun

(...) I can see why... :-) Shaun, this is one of the neatest ideas I've ever seen portrayed in LEGO. Well done! (...) You got me curios, now: what kind of spring-loaded tensioner would you use, and how would you place it? Pedro (23 years ago, 9-Apr-02, to lugnet.trains, lugnet.loc.pt)
