^Good point about the Gerstlauer trains on NTAG, since RMC has obviously taken cues from the other companies they've worked with surely the Gerstlauer trains are where they'd look first when coming up with their own design. Whether or not they use OTSR depends on a variety of factors that have nothing to do with actual safety though, including those damn insurance companies, clueless state officials, the park itself, etc... Oftentimes "safety theatre" is more important that actual safety requirements, but I'm sure they're smart enough now to really push for the lap-bar only design. I'm thankful that most firms are seeing the light and going that way now.
