3. it is necessary to adjust the technical standards of all AVE lines to each other,

4. it is in the same manner urgent necessary, to adjust also the standards of the use of the
EMU’s to each other. Only one EMU type should be used on the AVE lines. The optimiza-
tion proposal will be based on these statements.

3.9 Elimination of Alta, Alvia and Avant trains from AVE lines operated with
a speed of 300 km/h

Because these trains run only 200/250 or 270 km/h train paths of these trains come into conflict
with AVE train paths scheduled with a speed of 300 km/h. This topic now must be scrutinized.
Alta trains
The speed difference is too high. An Alta train does never delay an AVE train as figure 1 proves.
The present Alta trains Madrid - Algericas must be replaced by AVE trains in the section Madrid -
Antequera Santa Ana and by MD-trains in the section Antequera Santa Ana - Algericas. Passengers
bound for Algaricas (= always the minority in the AVE trains) have to change trains in Antequera
Santa Ana.
Alvia trains

This topic can be scrutinized by three train diagram studies. The first example refers to the AVE
line Madrid - Barcelona. It is shown in figure 3.
