We have built an Exhibition Layout, Ashdan Junction, (videos on youtube), 17ft x 8ft.

Its a double track layout with sidings. The loco control is all DCC and most locos are sound fitted.
Every section of track has droppers to bus bars, split into 6 areas.

All points are controlled by separate circuits with traditional circuits, with seep point motors, powered by Gaugemaster Transformers.

We run up to 4 locos at any one time, with standby locos in the fiddle yard.

The DCC system is built from a Roco Digital Starter Set, consisting of power supply 10764, feeding 4 off Multimaus Red Controllers.

We are finding Locos tending to cut out, and the glass overloads light up.

I believe we need to increase the power to the layout. can we just add another 10764, or do we need another unit. We purchased a 10765, but according to the instructions, we need to rewire the track.
We are not electronic experts and any help would be appreciated.
