It is actually a reasonably good source about news and trends regarding the business side of railroading. The "progressive" part in their title comes from their advocacy of government subsidies for Amtrak and light passenger rail. The site may not pass FR's ideological purity litmus test, but I find nothing wrong in gleaning news from any source as long as critical thinking is applied. Know thy enemy.
Completely agree, and no problem reading any source. I was just trying to get a feel for the magazines leanings.
