EMD AB6

The EMD AB6 were specifically built for the Chicago, Rock Island, and Pacific Railroad. Only 2 were built; numbers 750 and 751. They featured a single 1000 hp EMD 12V567 diesel engine. Another engine was added later.
They lasted for 30 years, and both were scrapped.
==History==
Built specifically for the Rocky Mountain Rocket, this locomotive was an EMD E6 equipped with a cab and a working pilot. The trains they worked on travelled as a unified train from Chicago to Colorado, but would later divide into two. The CRI&P wanted a locomotive that could look like an integral part of the train when combined, as well as being able to move under its own power. Because it only had to haul 3 cars under its own power, the AB6 only had 1 EMD 567 engine when delivered. The space for the second engine was initially a baggage compartment.
The baggage compartment was replaced by a second engine when trainloads increased. Later on the units were modified for Head-End Power, and were re-assigned to comuter service in Chicago. Both were retired by 1974, none were preserved.
