Starting the hidden yard

Later that day, we were able to build the throat and lay one section on each of the eight yard tracks. This gives you a view of how the yard opens up. In the first photo, you see that the yard will go into a curve right after the throat. We are just squeezing everything in, with a minimum radius of 62 inches on the interior track and maximum radius of 90 inches on the outer most track.
The track will come out of a tunnel where the roadbed changes from grey to black. We are using Atlas number 7.5 turnouts as large engines will have to go into the various tracks. They certainly take a lot of room but that is the price you pay. Each holding track will hold about 35 cars plus an engine. This should give us some operating flexibility.
