| Tony explored the ingenious railway safety systems of the Victorian era, focusing on the mechanisms that assisted signalmen. His talk covered the interlocking of points and signals, as well as the Block Section system and how these principles can be applied by modellers. | Tony explored the ingenious railway safety systems of the Victorian era, focusing on the mechanisms that assisted signalmen.

| Although PICs and other microcontrollers are commonly used today—even for simple tasks—there’s still a valuable place for digital logic. David introduced the fundamentals of logic functions and explained the more common logic families. He provided practical examples showing how simple logic gates can deliver useful functions for railway modellers. | Although PICs and other microcontrollers are commonly used today—even for simple tasks—there’s still a valuable place for digital logic.

| The talk briefly covered some of the theoretical aspects of wiring and then cover wire types and where they should be used. The second part was more practical looking at wire termination and discussed some of the types of terminals and connectors. Finally, a few general recommendations were made. | The talk briefly covered some of the theoretical aspects of wiring and then cover wire types and where they should be used.
