RRTracks is a great track planning program, but it hasn't been updated for Standard Gauge in years. Let's all give them a push!Subject: Standard Gauge track libraryDate: January 18, 2014 at 10:26:07 AM ESTTo: info@rrtrack.comWhen can we expect the Standard Gauge track library to be updated to include USA Track LLC, Ross Custom Switches and MTH Electric Trains sectional track? These companies are, and have been for several years, the source of all new track being used by today's Standard Gauge enthusiasts. I would like to purchase the new version of RRTracks, but it is useless without this update.USA Track LLC provides traditional tinplate track in 42, 57, 72, 84 and 87 diameter curves, and 7, 14 and 36 inch length straights. ("1/2" 42 curves also offered.)Ross Custom Switches offers 72 diameter and #4 switchesMTH Electric Trains offers both traditional and plastic roadbed Standard Gauge track.Here are the actual dimensions of the curved rails used in the products above:(Centerline diameters indicated in red. 42, 57, 72 and 87 curve tracks result in concentric circles that are on exact 7-1/4" centers.)STD42 (2.143 gauge, 2.268 c to c) 45º-8/circlearc=15.112, radius=19.241, diameter=38.482arc=16.002, radius=20.375, diameter=40.750arc=16.893, radius=21.509, diameter=43.018STD57 (2.134 gauge,2.259 c to c) 30º-12/circlearc=13.873, radius=26.496, diameter=52.991arc=14.464, radius=27.625, diameter=55.250arc=15.056, radius=28.754, diameter=57.509STD72 (2.125 gauge, 2.250 c to c) 22.5º-16/circlearc=13.254, radius=33.750, diameter=67.500arc=13.695, radius=34.875, diameter=69.750arc=14.137, radius=36.000, diameter=72.000STD84 (2.125 gauge, 2.250 c to c) 22.5º-16/circlearc=15.683, radius=39.938 diameter=79.875arc=16.125, radius=41.062 diameter=82.125arc=16.567, radius=42.188, diameter=84.375STD87 (2.125 gauge, 2.250 c to c)22.5º-16/circlearc=16.101. radius=41.000, diameter=82.000arc=16.542, radius=42.125, diameter=84.250arc=16.984, radius=43.250, diameter=86.500
