Mark, I have my fair share of derailments. But most of mine are usually involved in train movements to get at a area I’m working on. Or getting a car or engine to the layouts edge to remove it to be worked on. My thought process is more on doing the the job I’m going to do than running trains. When I do just sit down and operate a train. Running that train becomes my main focus. I seldom if ever have a lapse and forget to throw a turnout. Running more of a rural road. I’ve got into the habit of stopping the train and pausing while the turnout is hand thrown. Then stopping again to throw it back.
While a non derailing feature is nice. I think when you get past the major construction and just run trains it will happen less.
Mark, Best of luck with your upcoming surgery.
