It is a case here of a programme written in GPSS (General Purpose Simulation System) which permits the economic consequences of a given operating policy to be numerically indicated. Starting from data concerning the passenger transport requirements, the program calculates the best railway solution (or "offer") satisfying train running and "occupation rate" requirements. For this purpose, it publishes running schedule indicator tables, calculates the stock required for this traffic, and indicates numerically in several economic tables the cost of the equipment and of the passengers carried. This program is intended to monitor a larger number of railway variants for passenger requirements, route times, types of stock, operating policies etc. It has been built for a research project C -3 Nord, which concerns the traffic between Paris-London-Brussels-Dunkirk-Valencia-Lille. It is rapidly adaptable to any work network. It comprises 3000 instructions written in GPSS 360, fed through a data processing machine 360 75 or 370, and requires a processing time of 2 min. per simulation day and a storage device occupation of 650,000 octal digits.
