HEP changes

Postby east point » Fri Jan 26, 2018 11:30 pm

Observed trains 97 & 98 for 2 days at Orlando. Each time the HEP was being provided by the second loco. Is this a change in policy ? after noting this checked fuel remaining for 98 the first locos had fuel remaining 1700 & 1710 first loco. 1510 for second locos which seems to confirm this setup. Sight gauges seemed to indicate that as well but ~200 gallons hard to see difference.

No policy on which engine supplies HEP. If you use the trail makes for a more quite trip. Of course if something goes sideways then you gotta stop and walk back to the second unit, unless you have a train crew that can help trouble shoot the issue.

I would've thought for sure that HEP is on the trailing power for sound reasons. That's a noisy job. Do y'all wear ear protection?

Every trip, the F40s were louder. We do have sound studies done every once in a while. Stuff usually passes but hearing protection just makes for a nicer trip.

The locos I run have the HEP skid all the way in the back behind another set of doors, so you don't even hear it in the cab. Cab itself is pretty quiet compared to older units (the F40's were LOUD), but I also wear ear protection. On some units when notched out the positive air pressure in the high voltage cabinets leaks past the seals, causing a squeal that drives *me* insane. Some guys don't care but I have a sensitivity to high frequency sounds....

Doesn't the hearing protection make it harder to communicate with the train crew or the dispatchers?

Thats why radios have volume control.

The rare times I have a Genesis leading I don’t tend to wear hearing protection unless I have to go into engine room. Some people find them loud but I do not for the most part (even supplying HEP). Amtrak did have a list comparing the decibels in each locomotive cab and which ones were loud enough to cause hearing loss with no protection and I don’t beliefe the Genesis were high on the list, that’s not to say you still shouldn’t wear protection some people do in the electrics which baffles me.
