Switch Machines With A Common Coil Connection #3
All of the following circuits are designed so that the indicator LEDs have "Fast Turn Off". These circuits cannot be used with switch machines that have separate coils.

Tortoise switch machines are becoming popular these days. Again, follow the wiring directions that came with your model for proper installation. These are quieter and more prototypical than the solenoid switch machines.
Note that the switch machines on the real switches can be moved to either side of the switch. That is not illustrated here, as our software only shows the switch machines in one mode.
Wiring a Switch Machine
So far, we have talked about wiring tracks where trains travel around an oval track plan. To branch off the mainline, onto a siding or another oval, we install a track component called a switch or a turnout.
Then there's the familiar green colored form of a Tortoise switch machine. Further into the tunnel you see a couple of wooden braces, probably made from an old pallet picked up at a warehouse loading dock.
When controlling a DCC system, the user selects which locomotive or switch machine it would like to control. The user can then set speed or throw the switch... some sophisticated systems allow control of momentum and braking simulation as well.
Ina track switch, the bar connected to a manually operated switch stand or mechanically powered switch machine that moves the free ends of the points one way or another, allowing trains to take either the through route or the diverging route.
The turnouts are best painted with a brush. I also painted my switch machines with the Rail Brown paint. They aren't quite as noticeable now.
Point motor
A machine that mechanically operates a point. A switch machine in North America.
Pony wheels
The small non-driving wheels of a steam engine.
The old interurban and street railways had lots of spring turnouts. We can save the cost and hassle of two switch machines and simplify operation if we use Turnips when we add a true passing siding to the layout.
The signal lights on the layout are also powered by the satellite power supplies and are connected to the contacts on the switch machines showing direction. Illuminating the underground station in my bar, are five 7.
This will eventually burn up your switch machine and also drain power from the locomotive. If this in not the problem there may be an internal contact problem.
