Hornby adds five new HM7000 sound profiles for model locomotives

Five new sound profiles give HM7000 more room to breathe, and the spread says a lot about where Hornby wants the system to go. The latest additions cover a London Midland & Scottish Railway Rebuilt Royal Scot, the Class 390 Pendolino and BR Class 25, 33 and 52 diesel families, widening the decoder’s reach across steam, diesel and modern electric eras.

Hornby has also kept the upgrade path tightly tied to its own app-based ecosystem. Sound-profile installation can only be done through the HM | DCC app and only on HM7000-TXS decoders, but each download comes with more than 24 free unique Hornby sounds, more than 20 functions, several horn or whistle choices and ancillary sounds recorded from the prototypes themselves. Hornby also says HM7000 users can import named function maps for sound, lighting and motor control, and that different sound packs can be downloaded and changed later.

The Royal Scot profile is the one that speaks most directly to modellers who build around named trains and heritage motive power. Hornby says 46100 Royal Scot was rebuilt with a taper boiler in 1950, withdrawn in 1962, returned to main-line running in 2016 and is now stored at the One:One Collection in Margate. That makes the new sound set useful not only for LMS and BR steam layouts, but also for preserved-era scenes where a famous express engine is running in its later preserved identity.

The Pendolino profile pushes HM7000 into a very different part of the hobby. Hornby’s Royal Scot train-set page places the service’s origins in 1927 on the London-Glasgow corridor, where traction later ranged from Royal Scot and Coronation classes to Class 90s and Class 390 Pendolinos, so the new electric profile helps modern West Coast Main Line stock feel like part of the same story rather than a separate universe. The Class 25, 33 and 52 packs do similar work for BR diesel layouts, giving owners sound options that match the backbone locos many operating sessions already rely on.

That breadth is what strengthens HM7000 as a long-term choice. Hornby says the system lets operators change locomotive settings while the model is still on the track, and it has also expanded the range with Bluetooth decoders beyond sound alone, which suggests a platform built to keep growing after the first purchase. For anyone weighing app-based Bluetooth sound against a more established DCC sound path, these five profiles make HM7000 look less like a novelty and more like a library that can keep pace with the roster on the layout.
