This may be a silly question, but of course I’ve heart of RTA and LRT, but I see 40 Lines has “LST.” What does that stand for? Maybe it’s a typo, but I kind of assumed it wasn’t.

Not a silly question at all! Paging through it LOOKS like a typo, I didn't edit the rules all too much when I took over so I'll go ahead and flip that to IGT. Sorry it took so long for me to reply back, but thank you for pointing that out!
