@Mike0289 posted:I currently use Fastrack in my temporary layout but have played with Ross/Gargraves in design software (dreaming about someday building a permanent layout) and wondered about this. Does this hold true even for scale Big Boys, DD35/DD40/Veranda type diesels, etc? I'm imagining a "worst case" scenario where a large loco is on an inner track and a string of 20" or 21" passenger cars are on the next track out
Anyone have experience with this situation? Is the 4"/4.5" center-to-center enough with 063/072+ radius curves even for large locos and long passenger cars?
