Tolworth Cliffe Good Trains?

[BobUK45]

As Tolworth line is only two tracks and I am guessing the Schenker loco leads the trailers down the line. Then I guess it reverses into the good line beside Tolworth down track. But on the return through London the loco is leading. How do they manager to get the train on the up line with the loco at the front? With only access on the down line from the Schenker depot, beside platform 1 Tolworth Station.

It drives into the neck, propels the train through the unloading facility, then runs uses the second siding to runaround the train reattach to the wagons & then carefully propel the consist back into the neck, ready for departure back to whence it came from.
