At the annual Steam-Orama & Antique Engine Show yesterday, a vendor asked for help in providing information on a single cylinder engine he was previously told was manufactured by Northwest Engine Co. for A Casey Jones Track Motor Car. I am not that familiar with this website but do have some pictures of his engine which I researched in a 1926 edition of the Railway Engineering and Maintenance yearbook. This may be the forerunner group that later became A.R.E.A. and is now AREMA? It lists a picture of The Casey Jones No. 531 Inspection Motor Car, also Model 550 Heavy Duty Motor Car. I have seen the Casey Jones formerly at Carona, KS so this vendor's engine may be from a model 531! Anyone interested in the actual pictures and/or the yearbook pictures, maybe we can somehow exchange information. Joe G. Felin
