Agreed on 2 - which explains the situation here on this map, as it apparently mapped with reference to Geoinfo map

I do not have a definitive answer for now, and so the lines plotted are taking reference from satellite images available in osm. The copyright issue could need some further study. However, the current alignment of the train tracks appears to largely reassemble that on the government map.

Hi Kovoschiz,

(1) "name=" serves mainly to display primary name. I think we can at this stage establish that 舊羅湖鐵路橋 is a primary name which was acknowledged by the authorities.

(2) "old_name=" is for historic name for an element. In this case, however, it was a relocated component of the Lo Wu bridge and it currently demonstrates more as a commemorative historic relic, instead of a change in name. I think "old name" may not be able to fully explain the image here.

(3) Even so, "old_name=" should typically be combined with the current "name=" which presents a visual rendering on a map. This would be more in line with the main goal of a map.

Look forward to hearing from you. Thanks.

Hi Kovoschiz. Just a quick question for this. What's the guideline of naming the bridge structure in osm? One of them is using an unofficial name while the other is official. I imagine common name would be more preferred after all, which would be what my edit hoping to achieve? Thanks.
