Collection of Railroad Locomotive Booklets issued by The Railway Educational Bureau during the late 1940's to early 50's. Subject matter includes: Steam Locomotive and Diesel Locomotive pertaining to Running Electro-Motive Freight Locomotives and the Power Plants of Electro-Motive Freight and Passenger Locomotives. Collection looks to be part of a series but I only have 4. Lots of literature as well as photos pertaining to the subject matter. Very good condition. Great to add to one's Locomotive Library collection. Buyer to pay shipping.
