Sunday Train has long supported the Steel Interstate concept ... but Sunday Train is "merely" an online activity composed of my online blogging in various forums and your discussion in various forums.

However, since 2013, I have also been involved in the advocacy of the Steel Interstate concept in a more direct collaboration organized by the Backbone Campaign, under the heading of "Solutionary Rail.

And the Backbone Campaign and Solutionary Rail team were successful in gaining the support of the Washington Labor Council for a feasibility study.
