I have connected the upper deck via the helix and into the Staging Yard. The addition has seen another dedicated booster (NCE PB5) added that will service the staging yard, return loops and engine facility.
The helix power is fed by a PSX-AR, this provides the automatic reversing function and will also provided detection through a SE8C via the LocoNet for occupancy.
The video below shows a short local headed up by a Reading MP15DC entering the staging yard, via track two.
Hopefully by weeks end I'll have the remaining staging yard ladder and return loops connected and detection up and running too.
