The funding is the sources of revenue that are going to pay for something. It's not to say there aren't ancillary sources of revenue for public infrastructure other than general tax revenues and users. You could build a Tim Hortons at a transit station. There are ancillary ways of doing this, but they're not frankly material to the overall cost of a public infrastructure. If you think of revenues as your income, but financing as your debt, you can finance something, but eventually you need revenues to pay that financing off.
