At that cost won it raise train fares?
No. The cost of electrical traction power is passed on to riders and tax payers. Using the Levelized Cost of solar power can fix at $0.09 to $0.12 per kWh for 20 to 30 years. The difference between the cost of market rate grid power in out years and the fixed or levelized cost solar power over those same years is cost savings. And it is that savings that provides the ROI (return on investment) that enables fund of the project.
