SierraSoft Rails is a Building Information Modeling (BIM) software specifically engineered for the design of railways, accommodating both low and high-speed lines, as well as single and double tracks. Its core BIM functionalities empower users to produce, modify, share, and analyze railway information models. The software facilitates simultaneous design and information modeling, leading to significant optimization of activities and effective cost containment. It provides a complete suite of tools for design, policy control, information modeling, and quantities calculation within a single product. The parametric dynamic design capabilities allow for projects to be created with remarkable ease. Design activities, geometric-informative modeling, and the definition of the interoperable model all occur concurrently within a unified work environment. Users can effortlessly insert axes, define typical sections, set BIM model characteristics, and generate the finished project, drawings, and information models with a single click, thereby substantially enhancing design value. The software supports real-time modification and checks, drastically reducing design time through immediate 3D cross-section visualization on planimetry. Any parameter changes automatically update the entire project, enabling instant verification before final project creation and ensuring maximum control over every detail. All design and information modeling data, including geometries and associated information, are securely stored in the M3 Framework Database. This database serves as the singular authoritative reference for all project information, guaranteeing consistency across project data (plans, profiles, sections), information documents, and information models. SierraSoft Rails leverages this database to automatically generate all necessary information documents and models, with content and level of detail tailored to specific requirements.
