The blue EMD demonstrator had multiple numbers in the prototype (#1202, #1203, #1204, #1205, #1206 and #1207). The Caterpillar Demonstrator unit (#1201) was a "one-off" celebrating Caterpillar's acquisition of EMD (I'm ordering this one, but I'm tempted to order one of the other ones as well). Hopefully there will be enough pre-orders so the scale-wheeled versions aren't cancelled.
