This page describes how to shunt 3 coaches into reverse order, and set off in the opposite direction. This would occur in marshalling yards and sometimes at station platforms where a different arrangement of coaches was required.

 

Step 1 - The train approaches the loop, slowing to a stop

Step 2 - The train stops in between the two loops, allowing room for the loco to run around 

Step 3 - The loco runs around the train via the other side of the loop

Step 4 - The rearmost coach is detached from the others, and shunted into the lower loop

Step 5 - The loco runs back to the upper loop to collect the second coach

Step 6 - The second coach, as with the first, is moved from the upper to lower loop

Step 7 - The loco runs back again to the upper loop to collect the dark grey coach

Step 8 - After moving the dark grey coach to the lower loop, the train is ready to depart again in the opposite direction
