So, what exactly are "infrastructure charges"? Are they enough to pay off the cost of actually building the infrastructure, or just maintaining it? Or is it just some semi-random number that's more complicated?
I'm not entirely sure. I'm fairly positive that it is more than maintenance (about three times what I'd expect maintenance to be based on Madrid-Seville tolls of €10/train kilometer and average European annual maintenance of €30,000 per single track kilometer), but I don't know if that fully covers capital, finance, depreciation etc. Unfortunately my computer is suffering from a fit of catatonia at present which is hampering my ability to look further into it at present.
The interesting thing here is the infrastructure:rolling stock ratio. I'd have expected it to be a lot higher.
