I agree there is inadequate enclosure; but the width of the platforms is a limiting factor; the platforms only appear to be 3M wide; and for sure they want 2.1M of free-flow space for pedestrians at the minimum; so w/o a wider platform its unlikely that enclosure is plausible. That said, there were ways to address that at the design stage!
The non-continuous roof is just bizarre.
As a rider you rush to the stop to get out of the rain, but the first shelter area is crowded, you have to run back into the rain to get to the next shelter............sigh.
