I would like rail companies to designate front and rear carriages for mask-wearing only.

With signage up, I would feel comfortable asking someone to leave that carriage if I could point and say 'If you don't want to wear a mask please go into next carriage.'

This would help all the people who want to wear a mask and wish to be in a place where others do too. People like me who have to travel for work, who want to travel for leisure, who are living with chronic illnesses. People who were shielding and now want to get on with their lives.

It's no harder to implement than Smoking and Non-Smoking carriages used to be.
