In 2024 the EWR2 Grid (ETRS89 / EWR2 SnakeGrid) was extended eastwards as the EWR3 Grid (ETRS89 / EWR3 SnakeGrid). To the west of Bedford the EWR2 Grid is an exact subset of the EWR3 Grid; over this extent the EWR3 Grid replaces the EWR2 Grid. The EWR2 emulation file TN15-ETRS89-to-EWR2-IRF.gsb (CT code 9764) is a subset of this EWR3 emulation file TN15-ETRS89-to-EWR3-IRF.gsb; west of Bedford the content of the two files is identical."]]]
