Since the wear of front-rod bearings railroad switches induce switch failure, evaluation is indispensable. On other hand, various parts are adjusted so as to avoid derailment. For example, attachment position adjustment nut adjuster rod could enlarge contact force between tongue rail and stock rail. The extension front also used eliminate gap toe In this paper, bearing during switching operatio...

The feasibility of using railroad flatcars (RRFCs) as the superstructure for bridges on lowvolume roads has been investigated in two previous research projects at Iowa State University. The results of these projects verified that RRFCs are efficient and economical alternatives for low-volume road bridges. Two county engineers involved with the RRFC project cited cost as the main factor for choo...
