Hi Nomadic. Be under no illusions, FH is a busy station and you'll be lucky to get a seat on the Overground any time before 9.30am. If you're lucky you may get a seat on a train to London Bridge but you'll have to be first in the queue i.e. waiting by the door. The benefit of FH though is that at least you can get your own space standing down in the middle of the carriage, whereas at Honor Oak it's a bit of a squeeze (i.e. you're more crammed by the door) and at Brockley it's almost impossible - ok you're in zone 2 but it seems to be a fight for people just to get onto a train - who needs the added stress at that time in the morning! I had that problem when I got on the train from Wandsworth and it was a complete nightmare.
