Some SD24s had a walkway over the winterization hatch screens, presumably so maintanace crew could walk across them. We have developed some parts so you can add these details to the Atlas SD24 models with winterization hatches. The first photo show the parts as packaged and the second photo shows a screen installed on a model and a walkway set on the model.
If you are modeling a unit that did not have a walkway platform over the hatch screen, we have just the screens in our Kit #14772.
