Let's say the USA builds out rail infrastructure at the same scale as found in Europe, Japan, and China. What's that going to do to domestic fossil fuel sales?

Let's say the USA builds out rail infrastructure at the same scale as found in Europe, Japan, and China. What's that going to do to domestic fossil fuel sales? How about domestic vehicle sales? Airplane traffic and airplane fuel sales? It's very notable that the countries with the most sophisticated train networks - Japan, China, Europe - are also importers of fossil fuels. Since the USA is an exporter of fossil fuels, a collapse in domestic demand due to an efficient nationwide train system is not something the ruling oligarchs are interested in financing, it's as simple as that.
