Doing some more layout expansion with a "wye" junction (see attached logical diagram - not to scale!).

I plan to use Massoth reverse loop modules and, whilst I'm ok with the wiring, I just want to check my understanding of the impact of using metal wheels on rolling stock. This is -
However, if I have wagons/coaches with metal wheels drawing power from the track (e.g. lighting purposes) but which aren't connected to each other or to a loco, am I also right in thinking that the legs of the Wye and the reversing loop itself only need to be long enough to hold either the loco or the longest coach?
Sorry for what probably seems a dumb question but I don't want to lay track & wire in the reversing loop modules only to find I've created something which can't be used by some of my locos / rolling stock.
Thanks in advance

I plan to use Massoth reverse loop modules and, whilst I'm ok with the wiring, I just want to check my understanding of the impact of using metal wheels on rolling stock. This is -
- If I have a loco pulling coaches and/or wagons that have metal wheels but are not electrically connected to either each other or the loco, then as long as the legs of the Wye and the reversing loop itself are long enough to can accommodate the loco, then no issue. This is true for both single motor (e.g. Stainz) and double motor (e.g. Mallet) locos.
- If the metal-wheeled wagons / coaches are electrically connected to the loco - e.g. for lighting purposes - or I have an interconnected set - e.g. an RhB 3-coach Allegra set - then the legs of the Wye and the reversing loop must be large enough to contain all of the interconnected loco/wagons/coaches.
