Ground ambulances are generally much less expensive, with an average emergency run coming in at $800 to $2,000, depending on the region and other factors, according to J.D. Fuiten, secretary of the American Ambulance Association. During an emergency, when the aircraft show up, there's usually no mention of money.
The traditional electric motor on a diesel-electric or electric locomotive is a DC motor. Internally, DC motors have two main components: the stator is the stationary outside part of a motor. The armature is the inner part which rotates.
The diesel motors on a locomotive actually produce 3600-6000 HP based on the model and age. I'll have to talk to the locomotive repair shop at work, and I can get to you on how much actual HP goes to the wheels. I do kmnow that each wheel is driven by an electric motor and they are huge.
