Although most students of railroad history might not think of Wisconsin's railroad industry as a significant contributor to rail transport, many events that occurred in Wisconsin have affected railroading on a worldwide scale. Here is a timeline of significant events that have occurred in Wisconsin related to rail transport. This research is not a final document and will be added to (and periodically reposted to the front page) as more information becomes available. Because there is so much data to include in this timeline, it has been broken into sections by century. The first part covers 19th century railroad history in Wisconsin, events occurring between 1801 and 1900 (inclusive). The next part covers the 20th century, events occurring between 1901 and 2000, and the third part includes years that have elapsed so far since then and the present. Finally, the sources used for this research, both for data and for images, have all been listed in the bibliography.
