Southern Pacific engines 3436 and 3439 head south from Denison on October 22, 1988. The train will terminate at Miller Yard south of downtown Dallas. The SLSF and later BN used SP trackage for 13 miles from Denison to Sherman. The SP right of way from North Dallas to Sherman was purchased by Dart (Dallas Area Rapid Transit) in April 1988. Not long after this picture was taken, SP trains would no longer run trains to Denison. Disk 90
