Thanks for the kind words! I don't remember how much of your code is left in it, but I never would have started without your example. I never expected it to get this popular.
I just added the relative time display mode, so the display is how long ago each entry occurred. That might be handy for your case too.
I also made sure the rich-text tooltips show all the controls (what to right-click, what to shift-click, eyc.) But not sure how important that is for trains.
