I was under the impression OSM speeds were always entered in Km/h with the renderer then doing the conversion if required. Also chunks of this route were tagged in MPH and km/h so I did all km/h for consistency.

Railway:ETCS refers to the Safety system on this route ETCS Level 2. The Sectional Appendix (showing the boundrys and what safety system is published under open data on the Network Rail site.

To verify on the ground look for blue signs with arrows pointing at the track.
