I am beginning to work on two IM NP Reefers that I have had on the shelf for a long time. I am looking for more information on the R40-23 clones owned by the NP. From a list message I saved I understand Richard Hendrickson had an article about these cars, but I couldn't find it using the Model Train Magazine Index. Any help on locating the article or additional sources of information would be appreciated.Thanks.
