"Who is driving the train?"
Translation:Treni kim sürüyor?
sürmek = to drive a vehicle/animal
kullanmak = to use
[-e] binmek = to ride in/on, to mount (an animal), to board (transport)
When kullanmak is put together with a car object, it takes on the specific meaning "to drive a car" = araba kullanmak, which sounds like it is commonly used. (It seems like it can be used with other vehicles, but perhaps is not as frequently.) Sürmek is used with other vehicles, or with animals that are "operated". Binmek, with a dative object, seems to apply to larger vehicles that you passively ride in (bus, train, etc.), and to anything you personally ride/drive "astride" (bike, horse, etc.).
