# Talk:SMS Cöln (1909)

There is a huge difference between the data regarding the power of the engines in the English and the German Wikipedia. 19000 vs 29000 hp. Which is correct?--Andreas (talk) 12:09, 28 August 2019 (UTC)

Both are, curiously - the discrepancy is found in this line from the de.wiki class article: "Die als letzte Einheit fertiggestellte Cöln hatte eine Zweiwellen-Germania-Turbinen-Anlage, die 19.000 PS und 25,5 Knoten leisten sollte, und bei den Probefahrten 29.036 PS und 26,8 Knoten erreichte." - the engines were rated for 19,000 SHP, but reached 29,000 on trials. I generally don't use trials data for ship boxes because many navies had a habit of screwing around with absurdly light displacements, very well-trained boiler room crews, and other such things that did not reflect actual service conditions in their attempts to build "faster" ships than their rivals. The Italians in the 1930s were among the more notorious for these practices, but they were by no means alone. The Germans did similar things with their battlecruisers before the war, for instance.
