This locomotive completed the trio of superfasts: 05, 06 and 07 of the Deutsche Reichbahnen Gesellschaft.
The 05 was the ultimate in speed and the 06 could pull anything put on the rails at 150 mph, but the RAEUDL designers, not satisfied, found a way to complicate what was already going well. Here was born the project of the 07, a 2' and 3' three-cylinder single-expansion superheated steam engine with a tender a little out of order, just to fit the coal and water to make the Berlin-Königsberg without supplies, all at 150 km per hour with an endless row of steel cars behind...
Fortunately (sic...) the war took a direction not so favorable to these flights of fancy so the project remained in the drawer, until Abel Slazlo, responsible for emptying the ashtrays (at that time in Germany trains ran on time and you could smoke in the office, just like in Italy before the war...) used it to wrap the sausage on New Year's Eve 1948...
The difficult thing was not to recover the project, which no one cared about for a long time, but to eliminate that infernal smell of sausage, still present after 58 years and that was inducing my scanner to start a union dispute.
