I'm somewhere between interstitial & Rod, with a bias towards interstitial.
And honestly I think we should just start talking about trains.
I think there was a thread where trains were sort of focal point but now I'm too lazy to find out what it was called. (Kassy found it, thank you. I'm still wondering what 'buses' are doing in the thread's headline, if they're powered by overhead electric then maybe.))
I think this policy and solutions-section would be a place to talk about new train tech, advancements in routing efficiency, well planned yards to onload and offload cargo (we need to admit every property can't have a railroad beside it), optimal speeds of cargo/passenger shared lines, signalling, PTC, and how companies can compete in a network that is not controlled by shared authority (which is common in Europe). On the passenger rail, there could be some talk on how to diminish the empty seats and possibly about some new methods of coupling carriages to quickly (and quietly) add and remove them, so the stops on stations wouldn't be so short you can just get one suitcase out in the time allotted for a stop. This probably means carriages should have small multiple-unit type motors for shunting, could this be automated? When it is necessary to build rail to rail overpasses, any news on rail bridge/tunnel tech?.... U
a link to my blog, a very poorly constrained study on US passenger rail, attempting to get it to the European level of service (it's obvious this is a bit utopian, but less than some hyperloop-stuff):

Anyway, here's my image of European-level passenger rail network for US , thicker lines, golden bits would be totally new rail and most of the others would need an upgrade...
