Signalogic Systems



A System for Any Layout.

Realism and Simplicity.

Even though our system is extremely realistic, there is no need to write code or understand signal engineering to bring your system to life.

PLUS, the signal system will react just like the real thing!  The actual safety logic is in the modules under the layout so if a train is over a switch before the dispatcher's panel sees it, the signal system will be safe and not allow a dispatcher to throw a switch.  This is one of many realistic measures of this system.

No Computer Coding Required!

Draw your layout and You're Done!

Our software does the hard work; You simply draw your layout on a computer.  The only additional information to input is where you hook up the wires!  You do not even need a computer to run the system, the whole system works from the modules installed on the layout. In addition, the drawing you make to program the system is now your optional dispatcher's panel.
The average layout can be configured in an evening.

The system is so flexible that even modular layouts like the FREE-MO standard can interchange modules and still retain a working system with only a few minutes of reconfiguration set-up!



At the click of a button, you can revert CTC into ABS/APB if you want to run without a dispatcher.

This is handy when you have an operating layout that typically utilizes a dispatcher, but there are times when you simply want to run the layout without the extra requirements of requesting signals and switches.  In this case, the signals clear if the switches are properly lined and there is no conflicting traffic ahead.

What do they do?

Signal systems provide safety and efficiency to railroads.  There are different types of signal systems.  Some provide authority for trains to continue down the track, while others simply help trains ensure the track ahead is safe.

Trains and Braking
When you come up to a red light in your car, you certainly can stop.  This is not true for trains!  Trains must know a long distance ahead in able to stop or even slow down.  Signal systems give trains this advance information.

Signal systems are broken up into 'blocks'.  Each block is a defined length of track that is protected by a signal at each end.  The signal displays whether or not a train can safely enter the block as well as what the train must do at the entrance to the next block.

Automatic Block Signals / Absolute Permissive Signals were widely used in North America.  These systems display whether it if safe to travel from one station/siding to the next.  Generally, written permission is still required from the dispatcher.

With Centralized Traffic Control, a dispatcher controls a large territory remotely.  The dispatcher can move turnouts remotely and request permissive signals for trains.  Typically the dispatcher only controls signals at stations/sidings.  These signals are red until requested because with CTC, a permissive signals IS the authority to travel.
