Kit Blake from Infrae gave a talk about Railroad at the Plone conference in Vienna,but
unfortunately I was unable to attend because it was at the same time
that I was giving a lightning talk about Plone4Artists in the other
room. However, I sat down with Kit later to have a closer look at
Railroad. We quickly discovered that Railroad has some pretty demanding
dependencies, and the documentation on how to get it all set up is
sparse.

Fortunately, Jan Wijbrand Kolman had gotten it all set up on Kit’s Mac
laptop for demo purposes, and was available on IRC to assist me (“jw”
on #railroad).
