And one step backwards
Last week was an educational one -- unpacked a couple of cars from my Canadian and ran them around the track. These are long passenger cars with a lot of fittings underneath and diaphragms -- quite unlike the doddlebug passenger car and old heavyweight that I have been using for track testing. As I expected, found a bunch of problems on the upper level -- one somewhat expected and a couple that were not. The expected problem was really an assembly issue -- built a section of bridge track and the ends stuck up just enough to drag on the underside of the car. Looks like we are redoing that and filing the ends to taper vertically to the tie bed.
The other issues were ones of local curvature breakdown -- being too impatient to ensure that the entire arc was >24" (dont listen to senior management suggesting it would be really nice if x were done when the relatives and their kids showed up in a couple of days...). One nice, long arc had a short section where the radius must have been about 18"... ooops. All the stuff about easements really does matter. Was pretty ugly watching the cars bind and push the end up and over the track. Good thing it was a test run and I was there to catch the cars as they derailed...
So the solution is to rework the second deck and replace a couple of the unhappy #6 turnouts with curved #7s -- will post a before and after later on. Means that a number of turnouts get moved and restructured. Which impacts the trackplan on the control panel, which impacts.... sigh. Wish I had found that article about building up a layered panel earlier -- not making a provision for change in the panel was a dumb mistake. Was smarter elsewhere...
