ABSTRACT
Managing railway systems poses problems with different scope. One of these problems consists in determining the number of transport units that are needed to attend a set of trips, defined by their corresponding origins and destinations and their departure and arrival times. Alternatively, it may be of interest to determine how to use a pool of transport units to meet that demand in the most efficient manner. This paper presents an Integer Linear Programming model for addressing both problems. In particular, a case study is described, corresponding tothe C5 line, in the commuting railway system of the region of Madrid
