If the government uses our money to pay for their friends' investments in the railway industry, then we are just being used to line the pockets of the politicians' friends. The track company should be charging the service providers enough such that they have the finance to do their own investment, not give them cut rates and then plead poverty. If the railways are not a commercially viable business, and it seems that may be the case, then the government had no business selling off our assets. We can fund our own nationalised services without being forced to make the rich richer on top.
