Hello,

After many years of absence, I have started HO railroading again. I have a 7 x 3.5 meter room with a U-Shaped table setup.

I have two Marklin sets

On the RIGHT-hand side of the room I have a 6003 Transformer and a 6021 Control unit- this is connected to an outer circular C-track- recently completed and runs well around the room connected with a lift up bridge)

On the Left-hand side I have (not connected yet) a 6003 transformer,6036 controller and two 6040 keyboards. to be connected to a K-track.

The K-track is large and involved so the grandkids run the C-track- and I the K-track.

Somewhere in the middle I have connected two points with C-to K transition rails , so the C and K tracks are now connected and traffic can run from one to the other if we wish to.

The question:
Can I connect the transformer to the K track as well- to act as a booster. (in that case two transformers are connected to the track)
or
Should I just connect the 6036/6020/6040 to the unit to the 6003 transformer on the Right.
or
do I need to insulate the two systems from each other. But how can you then take trains across on the fly.

I am a novice when it comes to Digital.

I hope someone can shed some light onto this.

Kind regards
Richard from Brisbane Australia

Perhaps I did not formulate my question well enough

The issue is- can you place two ttransformers(each with their own controllers) on one track

Simple answer is "no". Not without isolation or other schemes as Rwill has already pointed out.
