“…The urban rail comprehensive inspection trainset is equipped with multiple inspection systems, but in some working conditions, inspection tasks only require the activation of a single or partial inspection system for data collection work, or the inspection system only needs to be activated in a certain section of the task. Due to the long running time of the trainset, if the inspection system that does not participate in the inspection task is kept on, it will consume a lot of energy and be detrimental to the lifespan of the equipment [3] . A method for applying intelligent PDU (Power Distribution Unit) to comprehensive inspection trainsets has been proposed.…”

The comprehensive inspection trainset for urban rail transit is a type of large-scale inspection equipment that conforms to the green equipment system and intelligent inspection concept, equipped with multiple types of inspection systems. The existing control mode of the trainset is that each inspection system operation is handled by a dedicated person during the inspection task, which requires a large number of following personnel and high trainset usage costs. A new control mode has been explored, which is based on automated perception and processing technology and proposes automated operation logic for comprehensive inspection trainset. It utilizes this logic to design a vehicle-mounted centralized control system that automatically senses task information, sets data collection parameters, and automatically turns on and off the inspection systems. At the same time, for periodic inspection services, or by utilizing the inspection tasks of electronic tag readers and encoders, a series of logic is set to replace the role of humans to determine whether the inspection system is working properly, and to obtain information on the activation end of the trainset operation to ensure the correctness of inspection data collection. The vehicle-mounted centralized control system system provides an automated inspection process for the comprehensive inspection trainset, enabling the trainset to have the function of being unmanned during data collection, achieving cost reduction and efficiency increase in trainset use.

The passenger rail transportation system is of strategic importance to the decarbonization of the transportation sector. The use of green hydrogen is an environmentally sustainable option where highly polluting diesel trains currently operate on non-electrified rail lines. This paper proposes a novel adaptive power flow management strategy for urban railway trains powered by a hydrogen fuel cell stack and electrochemical batteries. The fuel cell stack is not dynamically controlled as usual, but it operates in on-off conditions to improve its overall efficiency. It always operates at the maximum efficiency operating point when it provides electrical power (on state) without following the load power variations. Furthermore, the state of the fuel cell stack depends on the state of charge of the electrochemical batteries which is the controlled quantity. As a case study, it is proposed a simulation of a suitably redesigned hydrogen-fuelled railway train operating, over an existing non-electrified line, for the L’Aquila (Italy) urban transportation service. The main components of the railway line and vehicle powertrain are designed, and the hydrogen consumption for railway operation is estimated.
