...Except that...let me point something out here. This is the dirty little secret of modern PTC trains.
Let's start with the ratchet lap bars. Those bars have six positions. When installed in accordance with the factory drawings, the THIRD notch is about the same distance from the seat back as the traditional double bar, but quite a bit HIGHER. The fourth notch is closer to the seat back than the traditional bar, but about the same height. That leaves only positions 5 and 6 that are any closer than the traditional bar. This suggests to me that the ratchet bars may be more accommodating to larger riders, but also more likely to allow a rider to be thrown from the train! Heck, it happened on a European CCI coaster!
Of course, with the individual lap bars, it is also necessary to have the seat divider, which is a problem on Blue Streak because that seat is so narrow to begin with. I can sort-of see logic behind the high seat back (see my prior message) but in practice, once the block brake was fixed, I can see it causing more discomfort than it avoids. And the switch from sponge-rubber-and-vinyl seats to high-density water injected foam has led to a seat that can cause lower back injuries.
I swear, the Blue Streak seats are something that "seemed like a good idea at the time", a classic example of something born from conventional wisdom instead of engineering...
