The Big Helix: Running a Train on the Helix, Wiring, And More Roadbed (257)

Before we move up to the second and higher loops in the helix we need to check the track we just laid to make sure it is free of issues. Then I want to see how many cars a typical loco can haul up the helix. Finally we'll solder on some track feeders, install the riser blocks, and add the first section of roadbed for the second level.
