Another engineer was working on Lightning Rod stuff. It's not actually currently down because of the launch! He said that they have that working pretty reliably now. A piece of track has to be reprofiled because of unintended forces present. The clamps for the magnetic fins on the bottom of the trains were also causing some issues (they work fine but don't last nearly long enough). The company who made the LSMs were very secretive about their design, so RMC has had trouble knowing exactly what forces are present, and there are a lot and they are powerful. At least you know that they share our pain of not knowing secrets
He had one of the clamps in his office, which I got to look at and examine.
