Remember, you can never tell which way a train went by looking at its tracks!
More than a decade ago, I contributed to web site called frograil.com. The site presented railfan tours, written by people who lived and chased trains is several parts of the country. The site was later transferred to a new custodian for archival, and it continues to be available for reference. The current webmaster may be updating, but I need to contact him to see. If so, I plan to update the tour segments I researched so many years ago — there have been a lot of changes!
