Central Bridge:
The Heart of AutoTF’s Automation Technology
The Central Bridge is an integral component of AutoTF’s innovative railway automation solutions, crafted to seamlessly orchestrate and enhance train operations. At its core, the Central Bridge employs a Raspberry Pi 4, striking an optimal balance between budget and performance, making it a robust yet cost-effective choice for railway automation.

Advanced Integration and Connectivity:
Built on a Linux platform, the Central Bridge runs AutoTF’s open source software that utilizes an open API to facilitate flawless communication across various train components. It forms the backbone of a dedicated network, managed via a switch that allows the integration of additional devices such as mesh repeaters. This network architecture not only supports unlimited extended meshes—each powered by its own Raspberry Pi—but also enables expansive customization, from adding extra bridges and cameras to extending coverage across the train.
Designed for Comprehensive Coverage:
The network hosted by the Central Bridge allows for the direct connection of AutoTF Tablets, enabling staff to interact with the system in real-time. Additionally, the AIC-Base, a critical unit for autonomous control, connects over the switch to communicate and synchronize with the Central Bridge, ensuring a unified operation.
Security and Offline Capabilities:
The Central Bridge is designed to function completely offline, enhancing security and reliability, particularly in remote and unserviced areas. For instances where real-time data connectivity is necessary, the system includes an optional SIM card slot, facilitating remote monitoring and management. When trains arrive at stations or depots, the Central Bridge automatically uploads all operational data, maintaining a record and back-up of all activities.
Autonomous and User-Friendly:
Upon startup, the Central Bridge operates autonomously, requiring no human intervention to kickstart or manage train operations. This self-sufficient setup ensures that train activities are not only automated but also consistently reliable.
The Central Bridge embodies AutoTF’s commitment to pushing the boundaries of train automation technology, providing an intelligent, secure, and highly adaptable platform that stands as the cornerstone of modern, efficient, and safe railway systems.
