Few successful 0-4-2s with outside cylinders were built (notably some of Nord's Rhone type). The PLUTO represents an "Intermediate Train Locomotive" built for the Berlin-and-Hamburg. It was rated at 47 mph, indicating better riding qualities than earlier 0-4-2s built for the Prussian Eastern in 1856, but its outside, overhanging cylinders inevitably limited its rideability at higher speeds.
