Very good question AC, I hadn't really considerd it as I'd only bought the bridge ones to support the girder bridge sides as and when I get something permanent setup. Although I have to say that is a darn good idea 
I may have to get some more of those as they are not only good for Daiso but also fit the Takara PlaRail as well

Happily collecting things all my life...
