Siemens Charger Cold Weather Reliability
Posted by josephr33 on Friday, February 26, 2021 11:37 PM

I've heard some rumors that the Chargers are not doing well with the Midwest winter weather, but haven't been able to get details.  Does anyone know about this and how the Chargers have been performing otherwise.  Hope they are not duds as the long distance ones should be coming on the property soon.

I don't know anything specific, but I've heard the same. Though haven't heard about any issues with Chargers operating outside the Midwest.

I'd suspect that it has to do with the SCR DEF freezing in the unexpectedly cold temperature, followed by mandatory and perhaps unpredicted/unwarned engine derating when the flow becomes inadequate.

This situation was apparently a chronic problem for a while on the misbegotten EMD Spirit locomotives that went to Metrolink, and that was at higher range of ambient temperature.

So found a few things... Seems the locos are having all sorts of teething problems with electronics such as inverter failure, HEP issues. The units are also ingesting too much snow.
