future is the implantation of Level 2 as the

and once high level of reliability has been
achieved, the exclusive implantation of
Level 2 will be studied.
In conventional lines, the main
objective is to increase safety and to
increase capacity in the lines with high
traffic density; mainly the lines in the
suburban railway network. This has
to be achieved at the minimum cost
possible. Currently, a detailed analysis for
