A general description of the organisation of the fully automated Koriyama marshalling yard, together with commentaries on the tests carried out with the object of sorting wagons on two sets of herringbone sidings (type D and type S). In order to carry out this study, the whole of the operations involved in the marshalling of 3,300 wagons per day were controlled by two computers, one of which dealt with the sorting of the wagons in accordance with the description and destination of the loads, and the other dealt with all the marshalling and train-formation operations. The object of the study was: - to establish the average length of time during which the wagons were immobilised in the marshalling yard; - to study the rate at which the trains were formed; - to establish the optimum constitution of the rakes and trains in relation to the length of the sections of track in the two types of marshalling yard; - to ascertain the type of yard which is best adapted to a given method of train formation. The re-sorting of diverted and detached wagons was effected in order of priority. Ultimately, the two computers will work together, basing on the destination of the load. The above article also contains a description of the hardware and software of the whole of the installations, as well as of their uses.
