The idea with Projekt Black is to have a layout capable of running trains on a continuous run or operations on a looped track or even point-to-point with some shunting.

Because its DCC, powered by a Z21, all three modes are possible.

The images below will give you some idea as the layout is planned to stretch 3.2m down one wall, then 4.68m but past a window and then another 1.6m down a 3rd wall.

I thought the two “ends” would be the widest at around 600 to 900mm while the part past the window could be 300 or 400 wide so we can still open and close windows and curtains if needed
