I think that the loop you refer to is the inner track on the left-hand side of the upper diagram (I cannot read the track name due to the colour and size) . Assuming it is a DR5013 will handle that reverse easily, especially if you put it into traditional short circuit mode rather than using sensors. It should also handle the power one, unfortunately we cannot see all the plan to confirm that is the case.
?
As long as the auto-reversing section is longer than your longest train then there will be no issues.
I have 3 different places on my layout where I need reversing loops. Here is one of them.
Here is a copy/paste from the 3rdPlanit software of my original main yard design.
Green are double gaps, black are one rail gaps and the thin black lines are change of radius and not relevent.
I was trying to figure out if there was any way to use the DR5013 to sort out the reverse loop labelled BL70R in the diagram. The boosters are different in the connecting tracks.
Here is a re-design based on scenario 5.3 using S0, S1, S2 and S3 tracks. I did it to remove the use of multiple boosters and to do it the preferred way.
Obviously this loses a lot of storage inside the loop. There is room to add a turnout for more storage, but how does this interact with detection sections etc.
