I have an off-peak return ticket which is marked:
From: BRIGHTON To: U1256 LONDN
The ticket does not say "travelcard" anywhere.
Just what does that entitle me to in terms of LU travel? I'm scheduled to arrive into London Bridge – am I then able to travel to any station within the zones listed making any necessary line changes along the way? I can't recall if you have to go through barriers in order to change line, thus making it count as an 'exit'.
