@Norweger Yes, it should happen, but it doesn´t shut down for me. The temps just keep rising and rising, no alarm, no warning light "Kühlwasser Übertemperatur" nothing.... And still it is getting Hotter, even when idling or under light load. As if the cooling fans would not start up.... The Engine also does not cool down after shutting it down.... at least on my side.
I'm only speaking from my long experience as a ship's electrician, and I do not expect the Bahn to have the same guidelines. But I would like to see the temperatures be a tad more above 50'ish when the loco is hauling a lot of load
Like with own electronic projects, and people get hysterical over a component temperature of 70 degrees which burn your finger. Then reading the specs and realizing this is normal.
