Rail fares in the UK can’t be easily capped or subsidized for a few reasons. One major factor is the complexity of the rail network, which involves both public and private entities. Train operating companies, though regulated by the government, need to cover their operational costs and make a profit, which makes fare capping difficult. Subsidizing fares would require significant government funding, which is often redirected to other public services. Additionally, fare revenue contributes to maintaining and upgrading infrastructure.
