There is no affected area for you, the Up main line is fixed and you should go through with no issue.On 1E08, miraculously managed to store all my luggage and get my seat at Durham. It's full and standing, long holds at every station trying to get passengers to deboard (although I must say the train doesn't feel *that* busy). And we haven't even reached the affected area yet...
Maybe ever so slight congestion of a GTR/Thaneslink in area, as up slow blocked.
