Animated horse movie? (Forget the name pretty sure it was made in the 90's)?

So I'm rewatching all the good animated movies from my childhood. You know like the lion king...Tarzan stuff like that. (because everybody can agree that the nostalgia is just awesome) anyways there was this one movie I watched alot and I just can't seem to remember the name of it! It was about a brownish gold horse who gets taken away from it's like...pack or whatever you call it, and then it's put onto a farm. It's called King of the wild or something. I forget alot of details but if ANYONE knows what I'm talking about could you help me? I remember there was a train scene... I'm pretty sure it was made in the 90's. (Maybe early 2000's)
