From going through Lionel's website, I found a Southern Pacific in green made in 2006 with scale 73" drivers. I would say they are 73", so 1131-1135 in Lackawanna are the correct road numbers. You get enough orders, let me know and I will take pictures of which ever number you choose. I will then email them to you asap. I will go through all 13 DL&W books I have and send you everyone I find of that road number. Just remember, 1134 and 1135 had snow plows after one rebuild and stayed on till scrapping. I am all in for helping to get any DL&W engine made as close to original pictures as possible.
