That texture file is part of the texture folder for the route.
I know the needed files for this train (and class 230) are missing in the Simvliet 2020 texture folder, so I included the needed files in this package (otherwise, the destination dispays on these trains would stay black when driving in Simvliet). But the files for Rijndam are already in the Rijndam folders. So I will make the change there, and it will be available on the train with the Rijndam 2022 update.
