Minor correction: there are facing-point switches near Uptown for the freight crossover and near the OMSF. Still, the number on our system is pretty well minimal. It would be interesting to know more about how it happened — as I understand it, one of the purposes of an interlocking is to make this impossible (switch can’t be changed while a train is occupying the space near the switch, and train can’t approach the switch while it is not locked in one position or the other).
