The tender was launched in April 2018 by the Portuguese public railway company, Comboios de Portugal (CP). It provides a framework for the operation of alternative road services to replace the Lousã railway line, which was interrupted in 2010 after more than 100 years of operation. Since the railway was closed, the service has been provided by regular bus lines. Transdev will transport the inhabitants of Lousã, Miranda do Corvo and Coimbra daily on this substitution line.
