There is a report, see https://forum.openstreetmap.org/viewtopic.php?id=56886 that South Signal Street stops short before this junction.

Also the road geometry doesn't seem to match the Bing imagery.

Could someone local to the area please survey and correct as necessary.

Place of worship has no religion or denomination. Although it is likely to be Christian/Greek Orthodox from the name, this needs to be verified on the ground.

The main Euston toilets, on the main concourse level by platform 1, are being refurbished at the moment. I have therefore set the opening hours to constantly closed.

Please monitor and, remove this caveat once they are back in public used, or a firm date is known for when this will happen.

I have also added the temporary replacement, on platform 18. Remove this when the main ones are back in use..

These footpaths are tagging for the renderer; they don't exist. Moreover, the one nearest the marker requires mountaineering equipment, as you have to climb over the top of a statue.

Most of the paths in the main square are also tagging for the renderer.

I don't remember seeing anything like Trafalgar Panoramic when surveying around the statue yesterday.

It is also not in a sensible place, as the statue plinth would hide significant parts of the square from view, and, in my experience, this sort of panorama is not not named, so this also be a name is only a name breach.
