This paper investigates what role could play the 3GPP LTE in railway radio-communications. We study a first case of shared infrastructure where the train control traffic is subcontracted to a public land mobile network operator, and a second case of dedicated infrastructure where the LTE-like network only supports the railway communications. We highlight the multi-user scheduler as the key enabler for managing a heterogeneity of sensitive and best effort traffic, and propose a new scheduler that maximizes the best effort traffic throughput while guarantying the sensitive traffic quality of service.
