A1 class 4-6-2 No. 60163 "Tornado" crosses from the down line to the up line as it approaches Princes Risborough with 1Z27 "The William Shakespeare", 08:03 from Paddington to Stratford-upon-Avon. This move into the up platform was to allow the following Chiltern loco-hauled service to overtake and also an up Chiltern non-stop service to use the through line.
