Claim:
1. A method for providing communication services to a train while the train is moving, the method comprising the steps of: establishing communication links between a first and a second network gateways to the moving platform via a first and a second communication links, wherein the first communication link is configured to enable exchange of communications between the moving train and the first network gateway and the second communication link is configured to enable exchange of communications between the moving train to the second network gateway; setting Hierarchical-Virtual Private LAN (Local Area Network) Services (H-VPLS) to enable provisioning of Layer- while the train is moving, replacing the first communication link with a third communication link configured to enable exchange of communications between the moving train and a third network gateway, by using Pseudo Wire Redundancy (PWR) to re-route traffic from the first communication link to the third communication link while the train is still in communication with the second network gateway via the second communication link, allowing to provide continuous L ensuring that the moving train is in communication with two different network gateways at any given time while the train is moving, wherein each of the two network gateways is in communication with the moving train along a communication link that extends between the moving train and a respective network gateway, said communication link being different from a communication link that extends between the moving train and the other one of the two network gateways.
