• Abstract:
  This self-contained manual represents an updated version of the Train Make-up guidelines contained in Chapter 3 of AAR Report R-185, "Track Train Dynamics-To Improve Freight Train Performance - 2nd Edition" published under the Track Train Dynamics Program in 1979. It is intended to serve as a source of information for considerations such as train size and car placement, that relate to the make-up of trains. ; This manual suggests that for trains under 4000 tons total train weight (TTW), no special consideration is required. However, for trains of mixed cars over 4000 tons TTW, the manual suggests that the placement of long car/short car combinations be restricted within the consist, so as not to exceed a suggested maximum trailing tonnage for the ruling grade and curve combination for a particular route. The suggested values are obtained from either tables or curves presented in this manual. For special cars or car combinations the best current practice is described. The detailed calculation procedure for estimating the maximum trailing tonnage is included in Section 10.
