Rails and stile.
For me as a non-native English speak person the name looks me odd, actually I would expect the opposite if I compared against traditional railway naming I would expect that naming came from. The longest and more direct parts would be "rail" and the smaller transverse parts would be the stiles. It look me more "logical".
Oh, yes, I know natural languages are not strictly "logical" but perhaps there are something behind that naming I missed and I would like to listen you and perhaps I could find some logic at that name also.
Thanks for your feedback.
