You're right gurglypipe! Amongst other things I use OSM data in Mapsforge format to render on the Oruxmaps app. It appeared to me that the river was being rendered above the railway viaduct in Wetheral so just wanted to test if the absence of an explicit layer 0 was the issue. But on closer examination it is not the issue I thought it was. I could change this back but I don't know if it is worth creating another change set to remove something which is admittedly surplus but not incorrect. Happy for you to remove it if you wish.

Hi DaveF, thanks for spotting and correcting this. Tim.

Thanks, typo on my part, now corrected

Indeed, this is the transition point between where the way represents individual tracks and where it represents multiple tracks. But admittedly I should have split the way at this point and added a tracks=2 tag to the multi-track element.

I have done that and moved the transition point up to the junction so it looks a bit neater. There is still work to be done on extending the individual tracks south of here as they currently just stop…not that I am a particular fan of drawing individual tracks on straightforward running lines like this (I think the use of a tracks tag is a better option).
