Whistle Stop is one of two train stops the park has. From the train, you can see about 70% of the park and it makes some great picture and relaxation opportunities. The train even features a tunnel that goes through the cliff and right next to the waterfall. On the train you truly experience the beauty of Six Flags Fiesta Texas!   Whistle Stop •  Status: Operational •  Type: Train •  Model: Unknown •  Opened: 1992 •  Length: •  Height: •  Inversions: •  Speed: 15 mph •  Duration: 11 minutes •  G-Force: •  Other: •  Height Requirement: Warning: mysql_result() [function.mysql-result]: heightrequirement not found in MySQL result index 8 in /home/sfftnet/public_html/areas/crackaxlecanyon/whistlestop.php on line 144
