Welcome to the new version of European Tribune. It's just a new layout, so everything should work as before - please report bugs here.

By jove, you're right! Though, methinks part of the 10% for asynchronous AC electrics are auxiliary units.

Later in the same thread, I find this photo, too:

In the first line left is speed, right is target TE; the second line shows the target TE per bogie, the third line shows actual TE (from which power is just under 5.6MW); the next lines show target power in and out, then the actual metered electric powers, then the electric loss.

Unfortunately, the photographer doesn't say anything on continuous/one-hour, he just says the software menu of his locomotive [one of the first class 185 which was up-rated from 4.2 MW with the software change] said "5.6 MW". However, just found another locomotive driver in the thread claiming:

Zumindest die privaten 185er haben 5,6 MW Dauerleistung. M.W. wird auch nicht mehr nach Stunden- und Dauerleistung unterschieden.At least the private [class] 185 have 5.6 MW continuous power. AFAIK there is no longer a distinction according to hourly and continuous power.

Could very well be that the hourly and continuous ratings aren't meaningful anymore. I was told by an knowledgeable source that beginning with 185_051 for DB and 185_510 for the private operators all were built rated at 5.6 MW. This of course includes all Swiss owned locomotives. It was planned to upgrade the earlier DB locomotives, but perhaps this was never done. None of the earlier DB locomotives is homologated for Switzerland, but 30 are homologated for Austria.

Having thought about it - I think lack of distinction should mean that maximum power is limited by temperature control only. That may or may not be fair to customers, depending on the level of heating: if full power is available in winter, but not in the summer, then the same trains can only be run slower in the summer -- and the differene is not guaranteed by the maker. This should not be an issue for the BLS and SBB locos, which utilise de-facto one-hour maximum power on climbs, but it may be an issue elsewhere.

See half-sentence in brackets in my previous comment: the earlier class 185 were upgraded, the photo shows one of them (but the class 145 wasn't AFAIK).
