I saw this link to a Washington Post editorial on Train Orders:
https://www.washingtonpost.com/opin...869d18-6c37-11e9-a66d-a82d3f3d96d5_story.html
One sentence in it sums up the editorial board's position:
"Congress should at last overcome the special-pleading of rural railway stops and help Amtrak eliminate its wasteful long-distance service."
The WaPo, and particularly its editorial board, sits dead center in the Washington establishment. It's neither a Trump administration house organ or left wing propaganda. I interpret this to mean cutting long distance and beefing up corridor services is now reckoned to be centrist policy in the Beltway, and not some right wing conspiracy.
There's opposition on the left(ish) side – the union backed letter from blue state members – and the right(ish) side, from senators representing red and/or rural states, but I think both are bargaining ploys to wave the flag for constituents and win a few minor concessions, rather than effective counterattacks. I'm betting Anderson walks out of the meeting (more likely, walks into the meeting) with a done deal that gives Moran something he can claim as victory, and allows Anderson to move forward with the core of his plan.
