For SimSig · Windows

Realistic signaller-to-driver comms, built for SimSig.

RailComms is a virtual railway radio for SimSig. Drivers call you in real AI voices over authentic radio static — you answer and reply by speaking, call cabs back, authorise moves and handle emergencies. It even works SimSig's Train List for you.

Features

A real signaller's toolkit.

Two-way radio: answer drivers, call them back, authorise moves and handle emergencies — all by voice.

16 AI driver voices

British, Indian, Irish & Australian accents — sub-second latency.

Railway radio FX

Bandpass, PTT clicks and carrier hiss. Office calls play clean.

Push-to-talk replies

Hold a key, speak — your words matched to the right reply.

Drive trains by radio

Authorise passing at danger, examine the line, shunt, reverse or run non-stop — RailComms works SimSig’s Train List for you.

Emergency Group Call

Broadcast an emergency call to stop every train in an area, then watch each one come to a stand.

Live incident calls

Route Control, Station Managers & MOMs report trespassers or animals on the line — with follow-up all-clears.

Call any driver

Ring a cab — normal or urgent — or have the driver call you back the moment they stop.

Multiplayer

Player-to-player WebRTC voice and shared emergency calls, LAN or cloud relay.

Browser & iPad remote

Run the whole panel from any device on your network — or dock a tiny compact bar and work SimSig underneath.
