I'm not sure on India Rails. We did have one player who had never played a crayon rail game, so there was some time spent on rules, but not enough to account for 7 hours. There was a fair bit of extra time spent figuring what came from where, and where the various cities were, and I think possibly some of the floods, are a bit nastier -- there seem to be more rivers, and at least the Ganges gets crossed a LOT. (I haven't played Aussie or Nippon rails.) I think India rails might have been missing the doable smaller loads that allow you to run a lot of double-loaded runs or something, and it felt like there were more single-source goods than the others I've played (Eurorails and Iron Dragon).
