Tweetsie Railroad Extending Hours on Select Nights in July for ‘Cool Summer Nights’
June 18, 2012. Tweetsie Railroad is once again celebrating long summer days with extended hours of family fun on select nights in July during its Cool Summer Nights event. When the sun begins to drop behind the Blue Ridge Mountains, the day turns to dusk and the fireflies begin their nightly performance, guests will see the park in a whole new light.
