New version! Now, the main body is only 4x6 studs:

This redesign is absolutely brilliant! Time to make a couple dozen
automated switch points...

Thanks Chris, but apparently this design as it stands is too sensitive to the
clutch strength of the components being used. Yesterday, I ran it over 100
times without the hint of a problem, but today after partially disassembling
and reassembling it, it won’t go more than about 50 switches without
self-destructing. I think the primary issue is keeping the motor from
seperating from the base. Have to think about this...

I built one of Marks last night, and yes, even with the ‘closed studs’ and other
avenues of ‘keepin’ it together’, the plates adn motor do eventually come loose.
Sometimes it’s 20 times, sometimes it’s 60-80 times, but the unit does work
itself to ‘self destruct mode.
Let me tell you that when the Metroliner is zooming around the layout and all of
a sudden there’s a 2x3 panel on the rails... much fun and destruction ensues :)
Thank goodness some guy whom I can’t remember made up DCC for LEGO trains...
Full stop on all locos, thus preventing cascading train wrecks :)
Anyway, As for fixing... if there’s a way to get a half thick technic beam to
bound the bottom and top together... but I can’t figure out how--or maybe some
other ‘technic-way’ of locking the unit together...
I’ll try a few things tonight.

| (...) Dave, which version did you build (the 4x8 version or the 4x6 version)? My 4x8 seems to be holding together at the moment... knock on wood. I did notice that the transparent panels (vs. the opaque ones) are made of a stiffer material and seem (...) (21 years ago, 15-Dec-03, to lugnet.trains, FTX)
