Claim 19:
20. A method for a communication-based train control system that includes two main parts, wherein the first part includes a plurality of on-board train control computers, wherein an on-board train control computer controls the operation of associated train, wherein trains operate on a plurality of lines at a transit property, wherein on-board train control computers are provided by a plurality of train control suppliers, wherein the second part includes at least one virtual train control system that is implemented in a cloud computing environment with computing resources that are programmed to provide a virtualization of zone controller functions, and to generate control data required for the operation of trains on said plurality of lines and wherein at least one communication link provides two-way communication between said two main parts, comprising the following steps:
determining train locations and other operating data in the first part,
generating status messages that include said train locations and operating data in the first part,
transmitting the status messages from the first part to the second part,
processing the status messages in the second part in accordance with the virtualized zone controller functions to determine movement authority limits for trains,
generating control messages that include movement authority data in the second part,
transmitting said control messages from the first part to the second part.
