- Issues faced include non-availability of spare parts in depots, need for improved flushers, and leakage from joints.
Air springs of indian railway coaches
Air springs use compressed air inside a rubber bellow to provide suspension for coaches. This allows the coach to maintain a constant height regardless of passenger load. Air springs were introduced for hybrid coaches because heavy passenger loads would compress main springs and damage coil springs, compromising passenger comfort. The air spring system uses a height monitoring valve to add or release air as needed to maintain the required buffer height. When loads change, the air spring initially adjusts its distance from the coach body and then the valve adjusts air pressure until the proper height is reached. Maintenance of the air spring system requires trained staff and spare parts available at stations.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
