Is there an easy way to draw railroad diagrams

Question

Is there a way to layout graph to railroad-style diagram?

I wish to represent some syntax in visually-pleasant form. Like a results generated by "railroad diagram generator" (http://bottlecaps.de/rr/ui).

Answer 1

As a proof-of-concept, I adopted one of the sequence diagrams the railroad diagram generator generated for the XML grammar:

Corresponding GraphML file.
