Rather than climbers or as well as you could hook troughs to the outside of some of those railings and have fallers Something like this...
As was suggested, you could plant runner beans, sweetpeas etc but plant them in pots at the bottom of the railings so they climb up and through them.
Climbers tend to like a long root run so bear this in mind when choosing a pot. How would you fix climbers to the walls? Would it be easy to drill holes, nail etc?
The picture below has a grey courtyard but you really don't notice as the colours are so vibrant and also look how some of the pots are on chairs to vary the height
