I have a 2x8 layout underway. I had the board from another project. I picked up a Plymouth ($20, new unit) that seems to run fine with some 50 or 40 foot rolling stock around some pretty tight curves. Turnouts do not phase this little guy at all, I thought I'd have some problems with stalling like Shortliner said, but no problems here. I'll get some pics up soon. I know it will look a little less realistic with the very tight curves, but none the less I'll have a continuous loop. Thanks guys!
