Sleeping cars make sense for short journeys if they are parked in a quiet siding to make the journey last say 8 hours.
Queen Elizabeth made such a DOWN journey from Sydney to Orange, being parked in the UP refuge loop at Newbridge for a few hours.
She travelled wrong road from Gresham tto Newbridge to Newbridge, and special safeworking measures were applied, including clipping the points and hand signalling the "facing point locks".
This avoided having to shunt the train in the reverse direction into the Up loop.
