One of the regular posters over on the Atlas forum has come into possession of a series of 14 books, published in 1937, and apparently intended as material for a correspondence course, possibly in becoming a locomotive engineer. He scanned and posted a few pages as example, and the material looks extremely interesting. Original post here: http://forum.atlasrr.com/forum/topic.asp?TOPIC_ID=38615 After getting permission from the original publisher to reproduce and sell these, he has managed to get a firm to scan them and produce a CD with all 14 volumes on the CD, each one a separate pdf file. To quote part of his new thread on the subject: "There are 14 books, about 100-150 pages each. Each book is scanned into one .pdf file. All 14 files will be on the CD. I have received permission to resell these from the original publisher. All the files are fully TEXT SEARCHABLE. So you can open the .pdf file in Acrobat, search on, say, "injector", and it will locate that in the text wherever it appears. They were originally published in the 1930s by the International Correspondance School of Scranton, PA and they were used as part of a training course to train locomotive engineers, firemen, and other personnel. The volumes cover boilers, valve gear, locomotive operation, injectors, and many other aspects of steam locomotive design and theory. I had the entire set scanned, and I am selling copies of the CD that I am burning myself in the hopes I an at least recoup my expenses of having them scanned." His new thread, after receiving to finished CD from the scanning company, is here: http://forum.atlasrr.com/forum/topic.asp?TOPIC_ID=40492 I thought that some people over here might be interested in picking up a copy of what appears (at least to me) to be a very interesting source of steam locomotive operating information.
