My brother is travelling home from rural Scotland on a sleep train down to Euston, then walking from Euston to Waterloo on Thursday morning. He;s then catching a 9am train back to Winchester. He's taking all sensible precautions and has to come home to my mum's as he has no where else to go. We are in a support bubble with my mum who is currently living alone - healthy and in her 60's. We;ve had a baby 4 weeks ago. I'm worried about the risk of exposure but have no idea what London is like at the moment - is it busy in Waterloo like usual? Will it be less busy at this time of day? Ultimately we need to decide if we are having Christmas together or separately. Looking to find out more from people who have been to Euston and Waterloo recently. Thanks.
