Data from "Pluto", Editions Atlas Trains de Legend, #6 (1998).
Few successful 0-4-2s with outside cylinders were built (notably some of Nord's Rhone type). This sextet represents an "Intermediate Train Locomotive" built for the Berlin-and-Hamburg. Trains de Legend described this design as "certainly the most elegant 021 of its epoch." Moreover, placing the unpowered axle to the rear of the drivers supported the firebox without any need to adapt to a relatively high-placed powered axle.Moreover, the trailing axle helped to offset the "boxing" motion induced by the alternating fore-and-aft movements of outside cyilnders. Or so it was supposed.
The railwayrated the design's maximum speed as 75 kph (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. Before too long, the B-H added leading axle, creating a 1B1 (2-4-2)
