The other item I received was the energizer/stabilizer pen. Sounds very high tec doesn't it. What it is is a dispenser containing some kind of electrically conductive fluid that you put on the rails and the wheels of your trains to improve performance. Those who have used it have spoken quite highly of it. Running trains in a dusty exhibition hall takes its toll on the running quality of the stock so any trick I can use to improve performance I'll take.
So clean the track spread on the magic fluid and I'm good to go.
