Key Considerations for Installing RFID AEI Solutions in Railroads

When implementing Radio-Frequency Identification (RFID) Automatic Equipment Identification (AEI) solutions in railroads, the choice of tag and antenna configuration plays a crucial role in system efficiency. Three common setups include side with two tags and one antenna, one tag and two antennas, or placing the antenna underneath the sleepers. Each configuration has its advantages and considerations.


1. Side with Two Tags and One Antenna:

  • Advantages: This configuration provides redundancy as two tags are attached to each side of the railcar, increasing the chances of successful tag reads.
  • Considerations: The cost of deploying two tags per railcar must be weighed against the redundancy benefits. Additionally, alignment and spacing between tags are critical for accurate readings.


2. One Tag and Two Antennas

  • Advantages: Dual antennas improve read rates and accuracy by capturing RFID data from multiple angles, reducing the chances of missed or inaccurate reads.
  • Considerations: Proper antenna placement is crucial to avoid interference and ensure optimal performance. Additionally, the cost of deploying multiple antennas should be considered in the overall budget.

Standards like AAR-918S stablishes 2 antennas and 2 tags (one in each site). There is a big redundancy in this application and, considering the tag is the less expensive part of the solution, it worst the minimum error you can reach.


3.Antenna Underneath the Sleepers

  • Advantages: Placing the antenna underneath the sleepers protects it from harsh environmental conditions, reducing wear and tear. It also minimizes the risk of physical damage to the antenna. Also in situations where VANDALISM is a fact, this solution is the right choice.
  • Considerations: Achieving consistent and reliable reads may be challenging due to the distance between the antenna and the tags. Signal strength and interference become critical factors that need careful attention.


General consideration for Installing RFID AEI Solutions

Regardless of the chosen configuration, several general considerations apply:


Tag Selection

Choose RFID tags suitable for railroad environments, considering factors like durability, temperature resistance, and compliance with industry standards. Our “Transportation tag”, or Transcore AT 5118 is hightly recommended for Rail Applications.


Frequency

Select an appropriate RFID frequency (e.g., low, high, ultra-high) based on the specific requirements of the rail operation, considering factors like read range and interference. Most of Rail applications work on 915Mhz or 870Mhz (depending on the country regulation).


Integration with Existing Systems

Ensure seamless integration with existing railroad systems and databases to maximize the efficiency of data collection and management.


Regulatory Compliance

Adhere to relevant industry regulations and standards to ensure the RFID AEI solution meets safety and operational requirements (check for AREMA or CENELEC compliances).


The successful implementation of an RFID AEI solution in railroads depends on careful consideration of the chosen tag and antenna configuration. Each option presents its own set of advantages and challenges, and the decision should align with the specific needs and constraints of the rail operation. Careful planning, thorough testing, and ongoing maintenance are essential for a reliable and efficient RFID AEI system in the dynamic and demanding environment of railroad operations.

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. These tags may interact with automated systems to send additional information and are utilized for more complicated applications, such as thorough asset management. For asset tracking, both kinds are necessary, but full-frame tags are more adaptable because of their larger data capacity. 2. Signal Tags Signal tags are essential for contact with the railway's signaling system. When a train passes, they communicate with crossing gates, trackside signals, and other infrastructure to send critical information. Functions of Signal Tags include: Triggering signal changes (e.g., stop, go) Updating train schedules Sending alerts to the control center in case of issues By automating reactions to real-time events, signal tags increase railway operations' safety and effectiveness. They can even affect train speed and routing when combined with Automatic Train Control (ATC) systems, making train movements safer and more effective. 3. Tags for Harsh Environments TransCore is a pioneer in creating cutting-edge tag solutions for the railroad industry. Their solutions are made to function dependably in demanding settings, guaranteeing that railroad operations continue to be secure and effective even in the most severe circumstances. Harsh Environment Balise: A reliable trackside beacon that is incorporated into signaling networks. Balizes interact with trains to initiate particular operations, such as modifying the speed or updating the schedule. To ensure dependable communication in challenging circumstances, these tags are designed to resist high temperatures, intense rain, snow, dust, and vibrations from passing trains. Harsh Environment Tag: Similar to the balise, this tag is utilized for safety-critical applications, asset tracking, and train equipment monitoring. These tags are perfect for industrial regions or places subjected to extreme conditions because they are long-lasting, provide long-range data transmission, and are corrosion-resistant. High-Temperature Tag: Designed to function in hot conditions, such as those found next to power plants or in hot industrial areas. Because these tags can tolerate higher temperatures than regular tags, asset management and safety systems will continue to operate even in extremely hot or cold environments. The Importance of Tags for Railway Operations Tags are crucial to the operation of modern railway systems. Here are a few reasons why they are so important: Automation: By automating tasks like asset management, movement control, and rail signaling, tags help to lower human error and boost operational effectiveness.
