The "railway oriented programming" is pretty much the default way of coding in Node.js using the flow control module async. The major feature that async has but that I don't see in this blog post would be that you can split up the "railway" into multiple parallel paths when needed or when it is more efficient to do so, and then join the paths back together again later in a step which depends on the results from each of those parallel paths. Once I started using the async.auto() it completely changed my way of thinking about how code worked, and I've started coding in a much more functional style. Node.js makes this very easy.
