In 2013 Sporveien Oslo AS performed a concept study (KVU) for a new signalling system for the metro. The conclusion was that a Communication Based Train Control (CBTC) system with a semi-automatic train operation (STO) is the preferred solution.
In 2014 Ruter performed a quality assurance (KS1) of the above mentioned KVU, with the same conclusion.
In 2015 Sporveien performed a pre-project that resulted in a Steering Document for the project.
In 2016 Ruter performed a quality assurance (KS2) of the above mentioned Steering Document, with a recommendation of the project.
This Request For Information (RFI) is a follow-up of RFIs conducted in 2013 and 2015. These RFIs had a focus on defining a scope and a budget for the project. Now Sporveien is preparing a Request For Quotation (RFQ), and the purpose of this RFI is to get deeper knowledge on functionality, technology, capacity, implementation, operation, maintenance etc.
