Good Morning All!
31F @ 86% and dark. No new white so far.
Made progress on the Helix start yesterday.
If you remember, I decided to loose 2 storage tracks and opted in for 2 run through instead of one. Also am changing the inside radii for the 'down' storage and make the ramp skinnier. Red is the where the ramp will be situated. New inside track radii is 26 1/2". Since the NMRA site was bust, I setup the two inside tracks to measure clearances.
Outside is a Challenger, inside BigBoy and HW passenger car. Plenty of clearance for those.
The passenger car has more under hang needs more inside room but fits with about 3/4" to spare. I looked for a bit but did not find the 80/85 foot passenger cars, they are in the 'somewhere' place. So, just used a foot ruler centered between the rails and that had a little more under hang as expected, but also fit. I do not have any cars with truck bolsters a foot apart, so the ruler was probably over kill but good for this test.
Now that the testing is out of the way, framework for the Helix will start today; I think - Maria said something about CostCo and HD; don't remember if today or tomorra.
Later
[Edit] - forgot - track spacing in the Helix is 2.5". Mainline minimum radii is 36", branch 30" and the branch lines power size and train length will be limited. Currently thinking 10' trains and nothing bigger than 4-8-4's or BB diesels.
