HGK's DE 13, one of only three MaK DE 1024s in existence (the two others are also at HGK, named DE 11 and DE 12) drives through Cologne Main Station with a train of empty autoracks, and also casually proves that HGK is not superstitious.

The history of six-axle diesel locomotives in Germany is a little odd. While they were common, in various generations, in east Germany after the war, the western part never actually bought any. There were some prototypes based on four-axle locomotives, but the Bundesbahn (Federal Railway) preferred double traction of four-axle units instead, so they were never bought. The industry also developed some prototypes themselves, not based on any types already in service. The last such attempt before Germany was reunited was the DE 1024 by MaK. Using three-phase AC traction and with 3500 hp, it was quite a remarkable unit. But electrification was continuing, and then Germany reunited. Freight traffic in the former GDR decreased rapidly, so lots of class 130s and their various subclasses were available for free. The three prototype DE 1024, which had been tested under the designation class 240, were eventually sold to HGK (Hafen und Güterverkehre Köln), which is owned by the city of Cologne and maintains and operates the non-federally owned tracks and inland harbors in the area around Cologne. HGK did not order any new ones either, instead purchasing class 66s.

Huh. My sister says I always write too much comments. I think she may be right.

This loco is what the UK would classify as a Co'Co', three axles per bogie with all axles powered individually ie: by traction motors. At least at first glance that is what it would seem... Co'Co' is also part of the UIC Classification, or is it all the same thing?

The UIC classification for this is Co'Co', that's right. The difference to the english classification is only when it comes to steam locomotives (or odd diesels and electrics). Where a pacific is a 4-6-2 in the american and english notation, in UIC notation it's a 2'C1'.

Oliver Bullied, the same man who designed the A4 Pacific, designated all his Southern Region Battle Of Britain Pacifics using the UIC Classification rather than the Whyte Notation which was used as standard. A BOB Pacific is actually noted down as being 21C, rather than 2'C1', but I'm only going off Wikipedia so I might be wrong... :)

21C wouldn't make sense, maybe Wikipedia has a typo there, but 2C1, sure, that is a valid simplification. It gets problematic when you try to describe articulated locomotives or the Pennsy Duplex steamers that way of course, that's when you need the full notation.

Hmm, okay, I've just put that right on Wiki, personally myself, I much prefer the Whyte notation when talking about steamers, much simpler to understand. :)

I don't know, I prefer the UIC one, it makes it much more clear what is driving and what isn't. Not to mention that it's better for complicated locomotives, like the UP Big Boy. 4-8-8-4, well, what part of that is in what truck and how does it bend? (2'D)'D2' makes it absolutely clear. Another would be german 19 1001, a locomotive where each axle had it's own steam motor. 1'Do1' explains that nicely, but 2-8-2 would leave the important bit of information right out.

In the end, for 90% of the locomotives out there it's just a matter of preference, but for the final 10%, UIC is better. :D

Comprehensively, I agree. :)
