Subject: Sources Sought Notice: Mobile Railcar Inspection Portal (M–RIP) Solution–as–a–Service. The Federal Railroad Administration (FRA) is conducting market research to identify potential sources capable of providing a Mobile Railcar Inspection Portal (M–RIP) as a fully managed Solution–as–a–Service (SaaS) that meets all requirements in the attached Technical Requirements Checklist (Attachment 1). The FRA requires a portable, automated railcar inspection system to enhance safety and inspection efficiency. This system must be deployable to various remote locations without the need for permanent infrastructure investment. Key requirements include: a self–powered, containerized inspection portal capable of being relocated up to 12 times annually; high–speed, high–resolution automated imaging of the vehicle undercarriage and side–truck panoramas; automated defect detection using Artificial Intelligence/Machine Learning (AI/ML) with results delivered within near real–time (60 seconds); and a turnkey managed services offering where the vendor owns and maintains the equipment, providing remote inspections via certified personnel. Interested firms should submit a brief capability statement (not to exceed 5 pages) addressing their technical ability, past performance in wayside detection or similar rail technology, business size/status, and confirmation of registration in SAM.gov. The proposed solution must be a portable, self–contained unit within a customized 20–foot ISO container on a 30–foot chassis for rapid deployment.
