My arch at Supertrain only appeared to be supporting the bridge deck.
I still have to finish it properly, and plan to for GEMTS2001. A trestle
bridge would be nice, but consumes a LOT of black beams. (I do have
enough to make a nice one, yes, but at the moment I'm not planning to
do so.) I am also hesitant to make a double-wide arch bridge spanning
a full 60cm for the same reason - expensive consumption of beams.
As you know, I want to offer my bridges for sale - to do so the pieces
typically need to be unused. In the case of "T1", I plan to auction the
actual first bridge. In theory a double-wide 60cm span bridge could be
sold too, but to whom? Another LTC? I believe there is a market for
LEGO bridges, but the larger and more specialized I get, the smaller
that market becomes. In the case of a custom bridge, the sale is made
before the bridge is, the market size is one, and all I do is design
and build it - no "marketing" hassles. This is the ideal situation - Eric
[ http://www.ericharshbarger.com/lego/ ] has it made! (The set:770
Rescue Set is one of my childhood sets too - I managed to get a second
one in very good condition with box from Matt Chiles.) Anyway - unless
someone wants to commission a bridge for GEMTS2001... 8-)
If I wasn't so strapped financially, I'd have a massive collection of
pieces for building various projects purely for fun - like James'
collection, only larger. :-) If things go according to plan, in a
few years I'll be in that situation, (and be able to make a "Supertrain
layout" purely from my own collection) but for now I gotta focus on
more weighty issues than LEGO.
However, I have come up with a layout and bridge design that will IMO be
quite impressive. http://www.brickshelf.com/cgi-bin/gallery.cgi?i=41923
Here is an image of the layout (James - I've e-mailed you the TDL.)
The reason you don't see track on a couple of the areas on the left is
because that's where they're inside the mountain(s). Imagine a mountain
valley - there's "water" flowing down from the twin peaks - the peaks are
several decimeters above table level, and the lowest part of the valley
(in the foreground - underneath the bridge) is several decimeters below
the table level, perhaps with/as a lake/river. In the foreground the
bridge arches over the valley, anchored to the valley "walls" ~15 bricks
below the level of the tables. In the background a short arch bridge
carries the train between the two tunnels. The stream is only a few
bricks below the tracks of the small background "upstream" bridge, but
two or three dozen bricks below the main bridge. It's hard for me to
describe textually, but trust me - with James and I cooperating it would
look great. I could do it myself if James lent me his "mountain brick
collection", but he would undoubtedly do a better job of the mountain
valley, and I expect he would _want_ to do it himself anyway.
Probably a lengthier answer than you were anticipating, but there ya go. :-)
