Hi, thanks for editing this nice cycleway! Two  questions: 

1. It looks like you have _replaced_ railway=disused with disused:railway=rail but from the wiki it seems that disused:railway=rail should be _added_ to railway=disused (instead of replacing it) ?

See https://wiki.openstreetmap.org/wiki/Tag:disused:railway=rail

2. wouldn't "abandoned" be the more appropriate lifecycle  value, since the tracks are removed  ? (otherwise it would be hard cycling there)

See https://wiki.openstreetmap.org/wiki/Tag:railway%3Ddisused 

and my pictures of the cycleway : https://www.mapillary.com/app/?pKey=1823685241142147

Best regards!
