Greetings!
Sound Transit is requesting submittals in response to RTA/RP 0110-24 Series 3 Light Rail Vehicles. The submittal and question due date and time will be updated intermittently to align with each submittal phase; consequently, the initial due date displayed represents the due date and time for the Expression of Interest submittals, and updated thereafter to accommodate any approved extensions and/or to align with the subsequent submittal due date and time.
We have carefully reviewed the valuable feedback submitted during the recent Request for Information (RFI) phase, including RTA/RI 0106-26. We anticipate issuing initial updates in response via formal addenda approximately six weeks following RFP issuance. Please note that addenda may affect any part of this solicitation.
Note that Appendices to the Technical Specifications are available via the link below. You may need to request access and wait for approval before the files may be viewed.
