I propose we rename the notches on diesel locomotive throttles to the following:
I mean it makes sense, it controls how loud the locomotive screams and the ammeter that shows how much load you’re putting on the traction system is labeled in amps – A.
This A meter is pretty cool and it appears it’s been installed to a model railway for extra coolness. (This model of Weston meter is easy to open if you want a custom scale but this one looks 100% original!!)
And yes this does look like the right meter– EMD just put it behind a panel, likely with a small lamp behind to light the face. I’d post the link to the original if I could find it, but it seems the metadata on railpictures.net just doesn’t match up for me to find it. The picture is of an EMD GP7 cab.
