Paulo Raimundo, Secretary-General of the Portuguese Communist Party (PCP), used the presentation of the book Disaster on the Railway: 35 Years of Liberalization to launch a broader political criticism of railway liberalization and privatization in Portugal. At the event organised for the launch, he stated that the railway is a strategic public sector, essential not only for passenger and freight transport but also for national production, territorial cohesion, environmental protection, sovereignty and national development.
