Hi all! I am looking to model a New York Central switching yard. (Inglenook puzzle) in HO. It will run a GP35 and 40' cars. As I plan my freight, I've read that NYC system would often carry cars from every US railway. Can anyone back this up? Here is where I found it mentioned: http://www.trainboard.com/highball/index.php?threads/pacemaker-freight-service.20497/ Anyone have any other facts or resources about NYC? Any book recommendation? Thanks!
