Layout Description

 

The B&O Toledo Second Sub is currently under construction. The layout features Micro Engineering Code 40 track and handlaid turnouts. The mainline turnouts are #10, and the minimum curve radius is set at 24 inches. All mainline turnouts are powered by Tortoise switch machines and are controlled by the Dispatcher. Non-mainline turnouts are operated with slide switches, which also power the frogs.

 

The layout operates on Digitrax DCC, utilizing a DCS240 system along with DB210s, SE8Cs for signaling, and BDL168s for detection. Power management is handled with DCC Specialties PSXX devices. Both Digitrax throttles and WiFi-based throttles are employed.

 

The staging area features a 15-track mechanized sliding staging table, powered by a CNC stepper motor controlled by an Arduino. All staging tracks are the same length and are longer than the longest trains.

 

The passing sidings follow the prototype, with numerous interchanges with the PRR, NYC, and other railroads. Centralized Traffic Control dispatching is facilitated through CATS, running on top of JMRI.
