I pulled out the Sw7 that I'm using for running boards and for a drive. I found out my first attempt was too long to fit the running boards. I started to plan a longer frame for it, but when I look at my Alco book, the overall length of the T-6 looks similar to a S. I cut off the nose and removed a bit more material. It is now just the right length for the Sw7 frame and running boards. I'm going to let the glue dry overnight before I put the cut down grilles on.
I think the model I got is an S-1 since I noticed in my Alco book that the S2 has the vertical ribs in the grille. I think the round fan in the nose may be a little close to the nose on the T-6 than it is in the Rs11, but I'm going to call it good enough. As soon as I have the grilles mounted and the spaces filled in and smoothed out, I'll try posting a pic. I'm going to need to do some radical cutting down of the frame, and I'll have to find a can motor for it because the motor in my Sw7 is one of the W-I-D-E Athearns
