(For testing my LocoNet Block Occupancy and DCC Signalling Accessory Decoder)
This is a small (1400mm x 800mm) N-Scale test/demo layout designed to test and demonstrate the various DIY elements needed to electronically control a LocoNet based, DCC layout including a fully operational signalling system.
Below is a photo from above so you get some idea of the overall size and proportion.
Here's the view from overhead. The dimensaions are 1400mm x 810mm.
The length of the siding can accomodate about three locos.
I'm controlling the four turnouts with a MERG ACC4 Dcc Accessory Decoder kit. There are more details here
Here are some close-ups of the turnout motors. The little black box mounted under the veroboard is a 12V latching relay to switch the frog polarity when the turnout position is changed.
