Scott, I thought about your project a few weeks ago. On July 6, someone on the Facebook group — Ancestry.com Users Group — posted a message that she had just “saved” 4 pallets of railroad records from the Midwest early 1800s to mid 1900s — tax records, employment records, and a ton more info. A screen capture of her post and the pallets of railroad records is attached in the event you are on Facebook and want to reach out to her to pursue further research on the rail lines. If the attachment does not come through, email me directly for a copy. Barb
