In 2013, the Singapore government announced a plan to build the Cross Island Line (CRL), the country’s eighth Mass Rapid Transit train line. Since its release, the proposal has caused ongoing heated debate as it involves going underneath Singapore’s largest remaining reserve: the Central Catchment Nature Reserve. Following extended discussions with environmental groups, the transport authority later stated that they would now consider two route options: a direct alignment running underneath the Central Reserve, and an alternative route that skirts the reserve boundary. The authority warned that the skirting option could increase the construction cost significantly and cost commuters an extra few minutes of travel time. Intriguingly, in contrast to the underground rail project that threatens to further fragment the Central Reserve, another, more visible, repair work is taking place at the edge of the same reserve, aiming to reconnect fragmented habitat through an eco-bridge. Through these two seemingly contrasting yet intimately related case studies in a highly developed city-state, this article explores the complexity and ambivalence of urban movement and its entanglement with development, techonology and urban natures. How are the discourses of urban mobility directed by the desire for ‘velocity’, the politics of invisibility, and a fixation on certainty? What might it mean to reconfigure contemporary practices and ethics towards multispecies movements in an increasingly urbanised environment? Amid the growing expansions of infrastructure and public transportation in Singapore and around the world, often in the name of sustainability and liveability, this article unsettles some taken-for-granted, velocity-charged and human-centred approaches to urban movement and explores the serious need to craft new possibilities for a more inclusive and flourishing urban movement.

重新想象城市运动：在自然保护区，地下铁路和生态桥梁的交汇处

2013年，新加坡政府宣布了建设跨岛线（CRL）的计划，这是该国的第八条大众捷运列车线。自发布以来，该提案引起了持续的激烈争论，因为它涉及到新加坡最大的剩余保护区：中央集水区自然保护区。在与环境组织进行了广泛讨论之后，运输当局后来表示，他们现在将考虑两种路线选择：在中央保护区下方运行的直接路线，以及绕过保护区边界的另一条路线。当局警告说，踢脚板的选择可能会大大增加建筑成本，并使通勤者多花几分钟的时间。有趣的是，与可能进一步分散中央储备的地下铁路项目形成鲜明对比的是，更为明显的是，修复工作正在同一保护区的边缘进行，旨在通过生态桥重新连接零散的栖息地。通过在高度发达的城市国家中这两个看似相反但密切相关的案例研究，本文探讨了城市运动的复杂性和矛盾性，以及与发展，技术和城市自然的纠缠。对“速度”的渴望，隐形的政治以及对确定性的追求如何指导着城市交通的话语？在日益城市化的环境中，重新配置当代实践和伦理以适应多物种运动，这意味着什么？在新加坡和世界范围内，基础设施和公共交通不断发展，通常以可持续性和宜居性的名义，
