Didn’t Pioneer once publish this magazine? I miss it. Lots of info on short lines.
A Google search did not yield much. Pioneer was acquired by Patriot Rail, so it may have gone the way of the Dodo. I did find a newsletter from early 2022: chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://pioneerlines.com/wp-content/upl ... 202206.pdf
There was a web-page, but it is defunct: http://www.the-short-line.com/Subscription.htm
