The AEM7 replacement

Looking at that pic, it looks like there is some sort of blue material covering the horns on the upper right part of the locomotive. Any guesses what that is and if it is a common practice?

those are snow covers to keep snow out of Airhorns .

Easy enough! Thanks.

To answer the other part of the question, yes they are very common. Some are metal, others are more of the tarpish material like NJT uses. I think at one point Amtrak was just leaving these on year round on the engines since it's in a weird place on the engine that's hard to access.

Sounds to me like Amtrak is looking to retire the Metroliner cab cars. I'll be sad to see 'em go!

Er, from the perspective of the locomotive, the horns would be on the upper left part.

It's on the fireman's side. Who cares?
