Shoud i travel Pais bt the train without visa?

If you are a British national you do not need a visa to travel to France

Reading your other question I've seen that you are a UK resident with Indian citizenship. You will need a visa to visit France since the UK residence permit is not recognized as visa waiver by Schengen countries.
The won't let you board the train without a valid visa for France.
