I've referenced a picture on Railroadforums.com on the other thread I started titled First parts for the t-6 I have a book on Alco locomotives with pictures of the t-6. I noticed a difference between the ones in my book and the picture of the A & M t-6. The t-6s in my book have windows in the front of the cab looking out over the top of the hood like most switch engines. The pic on the other forum on the A & M t-6 shows some sort of box like housing on top of the hood directly in front of the cab. What is it? Does it go all of the way accross, or just cover the right front window?
