Allow repeat requests for the same line?

Very much subjective, but if I have the Victoria Line selected (for example) and want to check the status for it again (e.g. perhaps some time has passed and I want to check that the service is still good), I have to select another line, submit it, and then go back to Victoria. Or I have to refresh the whole page and select Victoria again

I think just pressing submit again will reload all of the information, it can just take a few seconds for the gif to update -- not the best user experience & something to fix.
