You have no clear space around the locomotive images. The locomotives in your images take up the whole 480 x 180px when they should take up less space in the image.
As you can see from the pic's you posted, 480px wide goes from the inner edges of the setup and info round buttons, and the 180px height goes from the bottom of the speed indicator to the top of the control buttons.
What your HC is doing in all the pic's is creating a white background for the load indicator and also a white background to write the loco number text on, you just don't see it on the third pic as the image has enough white space around the loco that the load indicator and number backgrounds are just white over white.
I don't recall the actual measurements I did for this and I'm about to fall asleep at the keyboard so I'm not going to look for them now but you first need to make the locomotive pictures slightly smaller, like GP in the third pic, and then increase the canvas size of the image to get it up to 480 x 180 (like putting a big white border around it).
It's easy when you know how but I can't concentrate enough to create any visuals to explain it right now
