Rail challenges: From both a technological and legal perspective, rail projects can produce bigger challenges than almost any other type of infrastructure projects. The next hour or so, my partner Jon Hart will be speaking about particular issues that they see as fundamental, including funding and financing aspects of rail projects as well as design, construction and some operational issues. There will also be time for questions.
