Hi, Welcome to OpenStreetMap.

There is access, (by your tags), to Way: 1193560233 so I've removed the access=no tag.

The railway platform being a linear feature is regarded as a footway, so there's no need for a separate footway. In any case you joined one end of your footway,Way: 1291220029, to a fence so it would not have been routable. I've removed the footway. If the platform had been mapped as an area then it would have been OK to map a footpath desire line across it. I hope this helps.

Regards Bernard.
