Thanks to both you and Frank for your help.
I had already suspected that the turnouts had a much greater resistance
(seemed to be common sense, and experimentation proved it out), but I think
I also had a fundamental flaw in my layout. My longest section was
connected to the main line only by two crossovers, and it was always in this
section that the trains slowed to an eventual stop. I wouldn't think that
the crossovers would have that high a resistance, but after rearranging the
layout to eliminate those, and adding a second power connection to the
"interior" loop, things are running smoothly once again.

You cannot add a 2nd transformer unless you separate the track (...) (25 years ago, 11-Feb-00, to lugnet.trains)
