Solutions can not only be derived from large projects. Small wind turbines and photovoltaic projects, particularly in connection with mountain railways and train stations, i.e., using existing infrastructure, could be quickly and inexpensively built. Rail operators would be able to reduce their costs and tap into new business areas. State economy would make sense in these areas. The burden on the taxpayer would be reduced in many places. Mutual profit and high-quality positions, and the resulting increase in operational capability and initiative, would be rather advantageous.
