Really? Looks pretty small to me. It's one of those ones that you feel like you are going to fall out of at every turn [big grin]. And if that is the case then there is no coaster of that type in the game (yet!), and none of the other types that are there have lift-tyre functionality in real life.
thats the whole point some of us are trying to make though, if they are truly going for realism, regardless of use, its all one in the same. its not about this coaster has it so its only used that way, friction wheels are a versatile feature for coasters and are not different from coaster to coaster, only in how its used, but the mechanism itself is the same thing used for many different situations, on different coasters.
if you wanna get real technical, drive tires, how they are used in planet coaster, for only rolling trains on straight track are actually usually facing up, not perpendicular. (which, by the way is missing from the stations...hopefully this isnt forgotten) depending on the coasters design itself. when used for acceleration and lift hills, thats when they are facing perpendicular to the track, and the trains design takes advantage of this....its because dual tires facing perpendicular to the track as opposed to facing up provides more grip for acceleration or lifting, the extra grip isnt really required for level track, so less tires are used and facing vertical, again, depending on the car/track design itself. the reason for all this is purpose and cost, perpendicular systems are more expensive and the extra grip isnt really needed for level track.
perpendicular wheels are sometimes used though for level track, sometimes. depending on weight and track design.
my opinion, if they are going for realism, is they should provide 2 versions, perpendicular being used for acceleration, lifting and even rolling. and drive tires, that they have now, facing vertical and only being used for driving on a level track.
