I know I'm speaking to two of the most 'detail oriented' people I've ever had
the fun of working with...
But you're thinking about this too much.
If we all agree on-
a straight equaling 10 inches
a quarter straight equaling 2.5 inches
a curve equaling 15 inches
ramps equaling 10 inches
a reverse switch equaling 5 inches
a switch--17.5 inches (I actually added the straight and the half curve)
a half curve equaling 7.5 inches
If we all agree on these parameters, then we can ascertain 'who has the biggest'
;)
I tried physically measuring the ramps, and seriously, the length that the
monorail train actually traverses isn't much more than 10 inches or a straight
piece--it's negligible. And if we're all agreed on the numbers above (or
whatever numbers you want to change them to--I'm good with that as well), then
that should be good 'nuff
As it is, DaveE's (et al) record is pretty much not going to be touched by me.
Though I may be convinced to try.
Going with this, I should actually inventory my collection again. As it was
inventoried 3 years ago, I have 276 feet of monorail track in my personal
collection. Dunno if that number's changed.
The latest OBB space layout has 146 feet of monorail track.
I can e-mail you guys the excel spreadsheet that I use to figure all this stuff
out :)
