Mother nature is a bitch.....
Anyway, most of the raised structure is just sand, comapacted together, they are supposed to reenforce it with concrete then put a drainage along the bottom...From that pic, you can see that, that had not happended............. The rain chipped the bottom part because there was no drainage, one it did that, it stated eroding the sand wich had not been reenforced, and like I said, mother nature is a bitch,..But you can see, its still structurally sound, a fully loaded train can still pass..
Anyway, the Chinese company contract is that they would maintain the rail for like 5years after its completed, so that any weaknesses, damage are repaired by them at no cost..
