Correct the operational restriction in the section corresponding to the Nare variant, which presents slopes of up to 1.8%. Restoring the original construction conditions in the section of the Nare bypass (minimum radius of curvature of 500 m and maximum longitudinal slope of 0.5%), the configuration of a standard train could be restored, with the maximum hauling capacity from La Dorada - Santa Marta or vice versa. The installed capacity for this corridor estimated in the &quot;Feasibility and Convenience Study of the Change from Yardic Gauge to Standard Gauge and its Impacts on Cargo and Passenger Transportation&quot; is 26,300,000 t/year in each direction. Progress and results LE3:  Adoption of the Iron Master Plan. CONPES 4047 - Contractual risk policy guidelines for ferred transportation.  Process of structuring the MRV system of the measure. Strategic line 4 (LE4): Change from road cargo transport mode to Fluvial Rio Magdalena Methodology LE4: The AM00090 methodology is used as a reference, it establishes the procedure for changing from road mode to a less intensive GHG emission in this case fluvial mode. In the baseline methodology AM00090, three (3) equations are defined to calculate emissions: 1. Equation No. 2 AM00090: Calculation of tons of carbon dioxide in baseline per year (BEY [tCO]). 2. Equation No. 3 AM00090: Calculation of the reference emission factor for freight transport (FE_BL [gCO/km*t]}. 3. Equation No. 3 AM00090: Non-empty return trip factor in the scenario of reference FRT,BL(fraction) measure 4. In the mitigation scenario in the AM00090 methodology, four equations (4) equations are defined (three taken from document AM00090 and one equation taken from the document &quot;Tool to calculate CO emissions, from the project or leakage from fossil fuels&quot;: 5. Equation No. 1 AM00090: Calculate reduction of carbon dioxide emissions per year (ERY (CO). 6. Equation No. 5 AM00090: Calculation of project emissions per year (PEY (TCO) 7. Equation No. 6 AM00090: Non-empty
