Thanks for the building tip. Gotta just love your building ingenuity.
These tips definitely save me a lot of time trying to figure out how to
incorporate these techniques. Man, that's one long train. Sure hope you
don't have any inclines on your layout. The decline of power on inclines
are one of lego trains worst weaknesses next to the building disadvantages
of steep curves. It totally amazes me how fast you put all of these great
train designs out for our viewing pleasure. Once again I say "kudos" you
are the man.
