Request for information (RFI) Solution for Stockholm Metro signalling system

CPV codes

Description

The purpose of this request for information (RFI) is to obtain more detailed information on selected topics, as specified in attached file. This is the second RFI and aims to improve trafikförvaltningens (TF’s) understanding of available solutions, technical approaches, and possible constraints. In the first RFI, TF asked suppliers to describe signalling solutions that could be offered specifically for TF and the conditions on the green line. Based on the responses received, TF now invites suppliers to participate in question round 2. TF intends to procure a solution for a new signalling system for the green line. The green line is approximately 41 km long with double track, of which about 26 km is above ground and 15 km is in tunnel. The current line has a total of 49 stations, with 37 above ground and 12 in tunnel. The current operational speed is 70 km/h. The Stockholm metro consists of three lines, the green line, the red line, and the blue line. The total track length is approximately 100 km with about 100 stations, of which 53 are located above ground. There are also ongoing and planned extensions and reinvestments in the metro system, including future replacements of signalling systems on the red and blue lines. The information is provided as background only and should be seen as a reference to support the questions in this second round.   Please follow the link below.   https://www.e-avrop.com/trafiknamnden/visa/RFI.aspx?id=4305 (https://www.e-avrop.com/trafiknamnden/visa/RFI.aspx?id=4305)
