Here we have a Lenz, made in Germany DCC add on controller. It is not gauge specific as that relies on the output of the main power supply being used. There are no leads or power sources as these can be added on to and existing system to give more controllers for the larger layouts. There are no instructions but are available on line .I have three available, two boxed although a bit rough but all the units were tested on our Club layout for operation and functional operation with no issues.
