I've just written a new sub-class of AIShip - AIGroundvehicle - in the context of a railway. Works well enough so far. Jon Stockill is testing it right now. We hope to extend it to a bus later. This is not a substitute for a decent ground vehicle fdm - it runs the train down a "flightplan" and back if you want. Just eyecandy. Subject to testing I will get it into cvs perhaps this week. I suppose really there should be a class "vehicle" with subclasses "ship" and "ground", perhaps even subdividing that further. That's the purist approach - meanwhile it's working - until Jon breaks it :-). During this development I discovered that SGGeod::fromGeodM(pos, 10000) now finds everything, not just scenery. So when trying to find the AGL of the train, it was finding itself. The hack was to disable HOT for the model. I don't know if this is the intent for SGGeod::fromGeodM(pos, 10000).
