Here is a thread of proof that High School Musical (Kenny Ortega) is obsessed with railings
So we start with the classic “Stick to the Status Quo”
Next we come to the first Gabriella ballad
Onto the second movie which had the least scenes, this one might be controversial since it’s a bridge?? But still a railing is involved
And finally for the third movie which had the most!!! We start off with “Right Here Right Now” of course in the famous tree house
Then we come to “I Want It All” which had THREE railing scenes in one song!!!
And next “Just Wanna be With You” 
Here we have a REPRISE of “Right Here Right Now”
And now we have the third Gabriella ballad with “Walk Away”
We end it with “I Just Wanna Be with You” again
In conclusion the high school musical series is obsessed with railings
