Abstract

A method of communication-based train control system migration includes scanning a guideway to generate surveying data and processing surveying data to calculate a 3-D representation of the guideway. Appropriate locations are determined for the communication-based control devices on the guideway. Communication-based train control devices are installed in a guideway at the determined appropriate locations and vehicles are retrofitted with an autonomy platform. Testing of the control devices and retrofit vehicles is performed. A communication-based train control system is used to control the retrofit vehicles when they operate within the guideway.
