Ensure all signage on the Oxford to Cambridge rail line is bilingual

Background

The new Oxford to Cambridge rail line has been classed as an England and Wales project, using funds that would've otherwise been used to fund rail projects actually in Wales. Therefore, I am putting forward that all signage on the line should be in English and Welsh, if using Welsh funding.

Additional details

All signage by default will be in English only due to the regulations already in place regarding signage in England. UK Government will need to make amendments to regulations, specifically regarding this project, to ensure that all signage will be bilingually in Welsh and English.
