Tags are essential parts of the railway sector that improve operations, increase safety, and simplify asset management. These little gadgets are essential for regulating signals, automating procedures, and supplying real-time data. This article examines the fundamental ideas of tags, their varieties, and cutting-edge Transcore-powered solutions. The Importance of Tags in Railway Systems Railway tags are small electronic devices used for data storage and transmission that are fastened to trains, signals, or other infrastructure. To manage schedules, keep an eye on train movements, and maximize safety, their main job is to connect with automated systems like Automatic Train Control (ATC). Additionally, tags improve overall efficiency and safety by tracking assets like railcars and providing real-time data for maintenance. Thanks to developments in tag technology, numerous kinds of tags that are appropriate for diverse situations and demands have been created. With the help of Transcore, some of these tags provide customized solutions for challenging situations. Let's examine the many kinds of tags and how they are used in the railroad sector. What is a Tag? A railway tag is a tool used to transmit data to a reader or control system. There are several uses for these tags, including: Identifying assets (railcars, infrastructure) Managing train movements Enhancing safety features (e.g., speed limits) Automating train control and scheduling To keep the railway network running smoothly, the tag's data is usually read by a sensor or reader as the train passes. Types of Railway Tags In the railway sector, various kinds of tags are made to meet particular requirements, such as asset tracking, signaling, and automated system communication. Let's examine the main categories of railroad tags. 1. Half Frame and Full Frame Tags These terms describe the tags' dimensions and ability to store data. In the railway industry, they are frequently employed for asset identification. Half Frame Tags: Perfect for straightforward tracking and identification in spaces with limited space or when less data is required, half frame tags are smaller in size and have a smaller data store capacity. Full Frame Tags: More substantial, larger, and capable of storing more info.
