What's New in Signal Cab Throttle

1.4

August 11, 2026

Z21 support, and your whole library backed up to iCloud. A third command station protocol joins DCC-EX and WiThrottle, consisting no longer asks you to pick a mechanism, and everything you've built can now live in iCloud. DC operators get momentum and sound. And the app now speaks Swedish. Z21 SUPPORT (BETA) Signal Cab now speaks the Roco/Fleischmann Z21 LAN protocol: speed, direction, functions, emergency stop, and track power, plus pulsed turnout control and CV programming on both the programming track and the main line. Add a Z21 by entering its address. Roster, routes, command-station consists, and per-track power aren't part of the Z21 protocol, so those stay unavailable on a Z21 connection. CONSISTS THAT SET THEMSELVES UP Creating a consist no longer asks you to choose a mechanism — Signal Cab picks it from your connection, using command-station consisting on DCC-EX and virtual consists everywhere else. Command-station consists write no CVs to your decoders, and re-register themselves if a station reboot drops them. Route each function to the lead engine or the whole set, drag to reorder members, and swap the lead engine from the editor. Please note: the advanced consist option has been removed. Advanced consists won't carry over after this update and can't be migrated — recreate them as regular consists. ICLOUD BACKUP Opt in and your locomotives, consists, turnouts and routes, macros, speed profiles, station profiles, and settings back up to your private iCloud — automatically as you work, or on demand. Setting up a new device becomes a restore instead of a rebuild, and if a backup already exists when you turn it on, Signal Cab offers to restore it rather than overwrite it. Off until you turn it on. DC OPERATION Virtual momentum (Beta) eases a plain DC locomotive up to speed and back down like it has weight, with Switcher, Road Diesel, and Heavy Freight presets per locomotive. Stop and Emergency Stop are always immediate and bypass the ramp. Horn and bell now play through your phone on DC, since a DC locomotive has no decoder to sound them. NOW IN SWEDISH The interface is available in Swedish alongside English, following your device's language automatically. CONNECTION FIXES • DCC-EX command stations are now identified correctly instead of being treated as WiThrottle-only — the manual "Switch to DCC-EX" step is gone • Fixed a JMRI connection that could silently time out against a loopback address • WiThrottle sessions now recover instead of stranding when a server restarts • Save a station you're connected to, so it stays in your list when it's off the network • WiThrottle is out of beta ALSO IN 1.4 • Smoother throttle — every speed step reaches your decoder instead of every fifth • Show All / Hide All and sorting (last used, name, address, run count) in the layout roster browser • A live command station log with a raw-commands filter, for when you need to report a problem • Configurable turnout state colors — keep Mint/Grey or switch to Green/Red • Hide unmapped functions on station-synced locomotives • The top-bar speed readout honors your Speed Display setting • Disconnect fits properly on iPhone
