BigFred turns your phone or tablet into a full-featured DCC throttle over your local network. Drive locomotives, manage your fleet, and coordinate with other operators — no app store required.
Open the app in any browser, pick a locomotive, and drive. BigFred works with Roco/Fleischmann Z21, LocoNet, and WiThrottle command stations, and lets multiple operators share the same layout at once.
- Web throttle — speed, direction, functions, and emergency stop from phone, tablet, or desktop
- Android app — native client with LAN hub discovery for phones and tablets
- Access control — user accounts and a shared vehicle catalog; each operator drives only their own vehicles
- Roster & consists — register vehicles and drive multi-loco trains as one unit
- Leases — lend control to another operator with time and speed limits
- Interlockings — coordinate busy junctions with radio chat and a signalman role
- Remote handsets — pair Z21 handsets and WiThrottle apps to vehicles in your roster
- LongFred — our own WiFred-based wireless handset for physical throttle control on the layout
