My expertise was on the Milwaukee E-units......I new just where you could wire around or block in relay's to make everything work ....such as transition for higher speeds or keeping the boilers(steam generators)for keeping the passengers warm.....when Amtrak started and we would get other RR's power between Chicago and Minneapolis things changed......I always liked the old CB&Q E-units as they had two steam boilers to heat the train.....and don't forget if you didn't have boiler heat you didn't have cab heat either....that right the cab heaters on the E7's and E8's was steam heat.....I think on the Milwaukee E9's it was regular cab heat off the manifolds.....correct me if I'm wrong......Thanks...Tom.

The 2 objects atop the roof are spark arrestors. Even diesel engines could be prone to emit hot carbon embers out the exhaust, which could still be hot enough to ignite a fire in the tinder dry mountain forests or grasslands during dry season. Many railroads had their own version of spark arrestor. The Milwaukee Road had very distinct ones that looked like a giant muffler.
