Description
In this work we propose a mechanism to optimize the capacity of the main corridor within
a railway network with a radial-backbone or X-tree structure. The radial-backbone (or Xtree)
structure is composed of two types of lines: the primary lines that travel exclusively
on the common backbone (main corridor) and radial lines which, starting from the
common backbone, branch out to individual locations. We define possible line
configurations as binary strings and propose operators on them for their analysis, yielding
an effective algorithm for generating an optimal design and train frequencies. We test our
algorithm on real data for the high speed line Madrid-Seville. A frequency plan consistent
with the optimal capacity is then proposed in order to eliminate the number of transfers
between lines as well as to minimize the network fleet size, determining the minimum
number of vehicles needed to serve all travel demand at maximum occupancy.
