Exploration of Railway Heritage Renewal Method under the High Line Park Mode——Taking the High Line Park in New York as an example

As an extremely successful case in the renewal of railway heritage, New York High Line Park has aroused the research of many scholars at home and abroad. This paper analyzes and compares a large number of existing cases to classify the existing railway heritage renewal models, and summarize the internal application characteristics and external manifestations of various models. Through the analysis of the common points in the design methods of the New York High Line Park, a representative case of railway heritage transformation, the three functional characteristics of the high line park renewal model are refined, and the combination mode of materials in the actual project and its use are discussed. Functional evaluation summarizes the modular methods of project transformation with the same internal factors, and proposes feasible transformation models. It is of reference significance for future Chinese railway heritage reconstruction projects.
