Morphology
railroad + vine
The noun 'vine' clearly signals that this is a type of climbing/creeping plant, so a learner who knows the constituents would at least infer the general category. However, 'railroad' does not transparently convey the specific habitat, growth form, or coastal-dune association described in the definition (and could be misinterpreted as a vine that grows by railways), and plant common names are often arbitrary. Because the category is clear but the specific referent and attributes are not predictable from the modifier, the MWE is only partially transparent.
Etymology
Railroad vine may come from the way its long, low stems run across the sand like small railroad 'tracks' and so it is a spreading vine. That's why railroad vine now means this creeping coastal plant.
