- The train will have a small magnet glued to the
underside to activate the switch
- These are miniature glass switches called Reed Switches
- The contact wires should be sleeved after you have soldered the wires
to them, small holes can be drilled between the sleepers outside the tracks so
the wires go under the base board
- The distance from the level crossing should be a little longer than the full length of the locomotive and carriages.
Position the Reed switch as shown in Fig 1, underneath the track between the
- First connect the Positive & Negative feeds, that's black (negative), Blue (Positive)
- this will give support
to the glass/wire connection as it is very fragile.
Figure 2 shows a section of double track around a Level crossing.
Figure 3 shows the wiring diagram for a fully automatic Level crossing lighting system.
First position the sensors and wire them as per drawing running wires back to a point where your PCB's will be
- One wire from all left hand Red lamps, and one wire from all right hand Red lamps.
Now Position and fix the timer circuit, and wire into this the 2 Red lamp wires, and the Positive and Negative feeds for you power source
- You will need two different types, one to switch ON the
level crossing timer and the other to switch it OFF
- Use long nosed pliers to hold the wires
between the glass and where you want to bend them
- Also the positive feed for the switches can be wired into the positive feed here.
Now Position and Fix the EM135 Relay card
To automate the Level crossing you first have to place sensors on the track to detect the presence of a train
- Connect Sensor 1 to the +V of the top Relay card
- Connect Sensor 3 to the +V of the lower relay card.
Now connect the orange wires from Sensor 2 & Sensor 4 to the COM on the right side terminals
- You should have 5 wires, 1 common Positive feed to each REED and then one wire from each switch.
Next wire the lights of the level crossing, when finished you should only have 4 wires leading to the PCB's
- Connect the Green lamps to the NC terminals
- One common negative connected to each lamp, One wire from all 4 Green lamps
- This is the latching of the Relay to allow the timer to pulse while the train travels from one sensor to the other.
