I think you are right there, but if that is the case I can't work out what that other landing with the railings is. I seem to remember the steps being almost opposite the 71 stand when the new bus station was built. There was a zebra crossing at one time and when you crossed it you had to go a bit to the left for the steps. The area changed so many times and so quickly it's hard to remember but is this the steps and landing on this photo' ?
