The design of railway route selection schemes has a significant impact on whether the railway can fully exert its carbon reduction capabilities.To assess the carbon reduction capability of railway route selection schemes,an analysis was conducted from the perspective of the full life cycle to identify the factors impacting the carbon reduction benefits of the railway's full life cycle.A corresponding carbon reduction benefit estimation method was proposed,and an application analysis combined with case studies was performed.The results show that:(1)The full life cycle carbon emissions of a certain intercity railway research section amount to 21.42×108 kg,while the indirect carbon reduction is 79.58×108 kg,resulting in a carbon reduction benefit of 58.16×108 kg.(2)The proposed estimation method for the carbon reduction benefits of a railway's full life cycle can effectively evaluate the carbon reduction benefits brought by the route design schemes.
