Baby's near railway death: Hindsight in design of railway platform?

Me and the Missus caught the news report on the baby who was literally rolled over by a train. From the CCTV footage, it's clear that the pram rolled towards the edge of the railway and toppled over just moments before the train came to a screeching halt. Everyone including the mother who was interruptedly rudely from her conversation with another woman, was equally astonished and shocked while they helplessly watched the train mow over the pram with the baby still in it.

See the full shocking video here.

I was shocked too. The moth flying around the living room could've just landed in my agape mouth. But the good news was that the infant was alive and escaped the tradegy with a bruise!

How in the world is that possible? It was very clear that the pram 'emptied its contents' onto the railway after hitting the tracks upside down. And the train went directly over it. It's a pure miracle!

That leaves me with one afterthought: Why is the platform constructed in such a way that has the slope declining towards the tracks? If you have noticed, the pram moved rather fast so that suggests the slope is quite steep. But I personally feel that it's a major fault that the Melbourne authorities have overlooked. We in Singapore don't face such problems but I think more could be done to prevent such things from happening.

We've seen many cases last year, where people have committed suicide by jumping onto the tracks. Why aren't the local authorities doing anything about it? What if an accident happens? Can't there be any grilles or glass windows to seperate the tracks from the platforms, like what they did for underground MRT stations?

I hope someone can take action soon, especially for the transport authorities in Melbourne. My heart goes out to the mum whose baby has miraculously survived the incident, and to those whose Sunday shoppings on a trolley have become pancakes once too often. Allelujah!
