On the question of meteor trails(trains) and the persistency. Aren't there several types of meteor trails? A fire ball I observed many years ago at a star party, we were able to observe with telescopes for a very long time. It appeared blue-green in color. For this reason I assumed it was an ion trail. This was certainly a lot different than the persistent trails left by the past Leonid showers which reflected sunlight quite white and I assumed them to be dust for that reason. Also they were snaked around by the high altitude winds. Are trails and trains the same thing?
I am amazed that people are able to tell how long things persist. I could not do that unless I deliberately timed it with a clock or stopwatch and I am also so fascinated by the event that the last thing on my mind is timing it.
