Go back in time when each interlocking was controlled by an individual tower. Run 8 Towers simulates a US&S Model 14 electro-pneumatic interlocking machine to control the switch and signals on Run 8 V3s Pittsburgh route.

Run 8 Towers is designed to have each tower manned by a friend where you will each coordinate which trains are coming and relay that information to the next tower.

You can throw switches, signals, add/remove blocking devices, add Rusty Rail tags, Time out signals and much more.

Towers “C” and “ALTO” even have CTC Machines!

Model Boards are heavily based on each towers real life layout, designed by Christian Currao.

Basic Instructions
To connect with Run 8, first enable Allow External Dispatcher in Run 8. Then open Run 8 Towers and select which tower you want to control. Right click the Model Board to connect to Run 8. If the occupancy blocks are pink, connection is NOT established. If there are no pink blocks, you’re connected.
You can move the window around by clicking and dragging the background (anything but the Model Board). Double-clicking the background enables full screen view.
Throw Switch (top) and Signal (bottom) levers by clicking and dragging them left or right. If there is a conflicting route, the lever will not throw. If you are throwing a switch, it will throw 2/3 of the way and hit a “bump”. Then it will verify with Run 8 three times, then you’ll hear a “click” which allows you to throw the switch the rest of the way. The functions are modelled on how this stuff actually works.

Right-click on Signal/Switch levers for blocking devices.
Hold Shift + Right-click on Switch levers to apply Rusty Rail.

That’s enough basic instructions for now, the best way to learn is to give it a try!
