Book excerpt: Two small towns in Texas, Tioga and Collinsville have a rich heritage and a mutual bond. Separated by only six miles, citizens of each have relatives in the other city. The silvery railroad tracks that stretch between the two towns have served as a liaison between Tioga and Collinsville--and the rest of the world--for many years. Both towns had train depots, but unfortunately, the depots went the way of the mineral baths and mineral waters of the past. Today, each town has its own municipal court, school district, post office, mayor, and city council. Although they are independent towns, they will forever be joined by their shared bloodlines and rich history.
