2.2 Vitoria-Zaragoza

2.2.1 Current Line

This case describes an ADST proposal between Vitoria and Zaragoza. As Figure 11 shows, in this
area there is a railway infrastructure that connects four important cities: Vitoria, Zaragoza,
Pamplona and Logroño, which could be considered as four different lines, but for convenience
they are assumed to be a unique infrastructure in order to define a global railway improvement
for the whole region.
