While apparently it can be used in that manner, I fear that it is much more common to describe things like railings along stairs. The fact that the subject is a posession fence has already been established.
In general, I need a word for a fence with vertical bars, something that literaly and figuratively would invoke the feeling of 'looking through bars'. If the first thought about 'railing' is that of a waist-high obstacle, the effect would be completely opposite to what I had in mind and thus the distinction is very important to me. Also, 'railing' already happens to rhyme with what I wrote.
