Just imagine the operating sequence to make this train up at Worcester - lets use this photo as reference. The line the Peak is on is the up platform road, then towards us we have up through, down through, down platform road.

So...station pilot (57xx) brings BSO and restaurant from Midland Rd carriage sidings and deposits them on up through road. Train loco (Castle) comes off shed, runs through station on down through road, crosses over and back on to stock standing in up through road.
Kidderminster portion arrives behind a Kidder loco (usually a 45xx or 51xx IIRC) in up platform road. Stops past scissors crossover which is half way along up platform, loco hooks off, runs forwards and then reverses over to down side and on to shed.
Hereford portion arrives behind a 4-6-0 (Castle or Hall IIRC), stops short of scissors crossover in up through road, loco hooks off, crosses over to up through road via scissors crossover, and then reverses over trailing crossover to down through road and on to shed.
So we now have loco plus 2 coaches stood on up through road, 4 coach Kidderminster portion stood past scissors crossover towards up end of up platform and 3 coach Hereford portion behind this with a gap where scissors crossover is.
Loco plus 2 coaches now pulls forward from up through on to up main and reverses in to up platform line, shunting all 3 portions together. Shunter couples up, brake test and we are ready for the right away....
What are the chances of that lot going smoothly every day? Must have been spectacular to watch - and still happened in late 60s with Warships and Hymeks although only the Hereford portion to add to stock from carriage sidings....
Proper railway operations!
