How to Wire a Model Railroad for Block OperationCommon Rail vs. Two-rail Wiring . When wiring blocks, you can either cut gaps in both rails or wire one rail constantly and only cut a single rail. This is called common rail wiring, which works well for wiring signals with most blocks. With reverse loops, you will have to cut both rails.
Wiring LEDs for Model Railroads 2 and 5 millimeter diameters, (see Figure 1.) The example below shows wiring for a three-color Type D signal using 3 mm LEDs for insertion into an Oregon Rail Supply type D target. It is quite useful to make a jig to hold the LEDs while soldering leads to them, as shown in Figure 4. The LED should fit snugly in the jig, but if it is too loose a small

GRS Thermal Relay Type T This relay can also be called a timer relay. You apply a voltage, and at some pre-determined time later, the contact(s) open or close depending on the relay's ...
LED Switch Signals The wiring diagram below shows how the signal lights are wired if two reed switches are installed inside of the switch motor. The two reed switches are wired together so that they act as a single SPDT switch. When the magnet moves to one side switch SW1 is turned on and SW2 is off. When it moves to the other side SW1 is off and SW2 is on.

Railroad Signals First, you will need some type of train detection device, to “tell” the signals when a train is approaching.There are 2 ways to do this: • Track circuit detector– This requires block wiring and detects the presence of a train on the block by the change in current that occurs when the train rolls onto that block. You will need track circuit current detector boards – one for each block ...
