BLOCKsignalling is a professional manufacturer of model railway electronics accessories based in the UK. Our modules are designed to provide the most realistic operation with ruggedness and long-term reliability key ingredients to ensure that they perform as expected for a long time to come. The BLOCKsignalling Simple Shuttle is designed to automate a DC model train running backwards and forwards along a single length of track.
An insulated rail gap at each end of the line stops the train until the track current is automatically reversed by the module and the train will start traveling in the opposite direction.
The time between each change in current direction can be varied by a simple screwdriver adjustment.
The timing is adjusted with a small screwdriver, which fits into a slot in the adjuster mounted on the PCB.
The adjustment is very fine for the first half of the rotation, setting the timing between 1 second and 90 seconds, then becomes coarser up to the maximum setting of 10 minutes.
At each end of the track, a small break is required. This can be provided by an insulated rail joiner or the track can be cut with a hacksaw, dremel or similar.
