Exploration of Urban Renewal Design of Railway Heritage Station Areas from a Perspective of Catalysts: a Case Study of Yiliang Station on the Yunnan-Vietnam Railway

The Yunnan-Vietnam Railway has played a significant role in Yunnan’s modern development. Its remaining railway stations are not only witnesses to the modern development history of Yunnan but also an important part of industrial civilization. Renewing and utilizing the railway stations along the line is not only of great significance to current urban stock planning but also achieves the protection and revitalization of railway heritage on the material level as well as on the spiritual level. This paper takes Yiliang Station of the Yunnan-Vietnam Railway as the research object. Focusing on the problems such as deserted railway stations，cut-off traffic of railway， and the lack of railway cultural heritage， this study introduces the catalytic theory to leverage its point-line-plane synergistic effects. The aim is to construct an integrated urban framework that connects rural areas， railways， and urban spaces， optimizing functional layout， traffic organization， and spatial configuration， etc.Through a development path that integrates railways with parks， tourism， cultural creativity， and other elements， this study explores the renewal design required for the development of related railways and other industrial heritage， and provides insights for the renewal and transformation design of similar railway industrial heritage sites.
