RFI Onboard signalling system for Stockholm Metro

Trafikförvaltningen hereby invites interested suppliers to respond to this Request for Information (RFI) regarding the possibility to adapt an ATP onboard system to Stockholm’s current relay-based speed monitoring solution on the red and blue metro line vehicles. This RFI aims to gather information from the market to increase our understanding of available solutions, suppliers, and capabilities. This is not a call for tenders and does not obligate Trafikförvaltningen to initiate a procurement process. Participation is voluntary and not a prerequisite for future procurements. However, Trafikförvaltningen have concrete needs to establish technical concepts in a short timeframe and launch upgrade projects. The use of onboard system is a strategic issue.
