So today was spent working on the two transitions from the future staging level and the finished layout level where the helix exits onto the return blob. I also cut & set in place the blocks for ruling grade on the first loop.
The last section of the last loop transitions from a 28"R to a 24"R to allow for the layout track work to connect. I have tested this section of track with both 40', 50', & 60' rolling stock and all run smoothly through this section...
With the helix to layout transition I decided to run Code 100 all the way up to the Code 83 #7 curved turnout where the helix connects with the layout track work. Because the helix & staging area will eventually have its own NCE booster, PSX-1 Circuit Breaker and Detection this join needed to be double insulated.
I managed to get the alignment between Code 100 & 83 really well aligned. This was achieved using track pins & shims, the insulated rail joiners are Code 100 and allowed the Code 83 to be manipulated to align with the top of the Code 100 rail.
The transition from the helix to the staging level needed some adjustment to the layout framework and tweaking of the curve leaving the helix. I had to add a short section of straight track to get the alignment to work, but the added benefit will be that it allows for a re-railer to be installed before entry into the helix.
Next step is to secure the blocks between loops with white glue and finish off the track work from the helix into the staging area.
