LIFE HUELLAS project has faced some problems due to political situation in Spain last year. The absence of Gobernment for more than ten months has meant above 80% reduction on public civic works. This special situation has impacted severily on project planning due to the impossibility of performing pilot tests on real railway projects. So, LIFE HUELLAS consortium requested an amendment to extend project deadline until March 2018, i.e. twelve months more, that was accepted by the European Commission.
