Abstract: To boost the development efficiency of internal application systems for railway enterprises and accelerate their digital transformation, this paper researched, designed and implemented an enterprise-level low-code development platform. Adopting reusable application unit design, the platform supports on-demand import and export of applications to accelerate the rapid construction of reusable business applications. It adopts a multi-tenant isolation model to realize secure data and application isolation for different enterprise users. Equipped with a multi-data-source storage architecture, the platform effectively meets enterprises’ requirements for multi-source data governance. Built on a dual-mode technical architecture, it enables flexible switching of deployment modes and seamless cross-architecture migration. Relying on a visual drag-and-drop designer, the platform supports efficient business form development. Practical applications indicate that the platform remarkably improves the reuse ratio of application units and the development efficiency of railway information systems, thus verifying its feasibility and practicability in low-code development scenarios. This study provides an efficient, flexible and extensible digital solution for railway information systems, and lays practical references and technical foundations for the construction of low-code platforms within the railway industry.
