Countrybusdriver,
I echo what has been said, never cross reds. A polite call on the R/T will soon bring up a green route/line up if pertinent. Please bear with us at the holding point when on the reds and greens, we have to wait until the cockpit of the a/c ahead has gone over the stop bar before we switch the greens, and it is a very awkward operation. I'd recommend coming up to the tower at night so you can get our perspective!
