According to a Skyline Attractions engineer, Bombay Express has these trains because longer ones would require milder hills, and that the park's capacity needs aren't as high. It's an unusual design choice for sure, and one that I'm holding out opinions on until we get more testing footage. That being said, I've always been excited for Bombay Express, primarily because of how far of a departure it is from GCI's typical designs (even Texas Stingray) - it feels more like a Gravity Group/CCI than a GCI, to be honest. It looks like one of the better GCIs for sure!
