Description of Issue

Turnout T326 is on the mainline in front of the Sonora Station, where the B320 and B321 blocks merge into B330.
On the picture below, we can see the track lifted at the end of T326:

I had noticed the track on one leg of the turnout seemed loose in the past. This time, it got worse. Interestingly trains have no problem when they go “up” the turnout, from B321 towards B330, and so this has not affected the Saturday operators. It’s only the mainline automation, which operates as a back-and-forth shuttle, that started derailing on this spot a couple days ago.

Description of Fix

I’ve attempted a preliminary quick fix:

I found that the track was already spiked, yet the spikes were “floating” and not holding strongly.

I removed the spikes I could find, and added some white glue. I tried to lift the track and apply the white glue below it, although I was a bit limited by the lack of clearance, and the area seemed a bit dusty. I then reapplied the couple spikes I found and added a few more.

I then cleaned the top and the inside of the rails to make sure they had no glue, and ran the automation train a few times at various speeds. The track seemed to behave correctly, as did the engine.

Glue notoriously doesn’t hold too well to dust, so I will want to re-evaluate the quality of that fix later once the glue dries. Plus, looking at the last picture, I think I still see a couple ties loose on the left side.

Fix time: 15~20 minutes.
