Commercial context
The reporting evidences staged delivery under a concessionaire model: five stations of stage 1A are already in service; stage 1B (11 stations) had averaged 96% civil-works completion and is reported by the concessionaire to target commercial operation in 2029. Stage 2 and the Line 4 branch are reported at 91% and 66% civil-completion respectively, with the concessionaire projecting October 2030 for commercial operation of stage 2 and the branch. Ositrán previously noted shifting schedule proposals and absence of a single agreed construction schedule between the MTC and the concessionaire; earlier regulator commentary in February reported alternative handover and indirect transfer options. Reported public financing comments include a ministerial investment estimate of about $5.35 billion and presidential reference to a supplementary credit of more than 8 billion soles that includes Line 2 funding. No first-party contract values, rolling-stock suppliers, or operator names were disclosed in the cited material.
