Hornby R3395TTS RailRoad LNER A4 Class 4468 ‘Mallard’ Steam Locomotive (Era 3) — 00 Gauge, 1:76, DCC fitted with sound
Product description
What it is and why people look at it
Hornby’s R3395TTS model is a steam locomotive for a 00 gauge train set, finished as an LNER A4 Class engine in Era 3 livery. The headline here is the combination of a classic subject—4468 ‘Mallard’—with a DCC-fitted setup and onboard sound, which is exactly the sort of thing that tends to appeal if you want your layout to feel less like a toy and more like an operating scene.
It’s also the kind of model you’d generally consider as part of expanding a roster, not as a one-off novelty. On paper, the level of detail and the DCC-with-sound angle are meant to make it satisfying to run for adults as well as being a collectible gift.
Key features at a glance
What stands out, based on the information provided, is that this is a Hornby steam locomotive model designed for robust, smooth running in OO gauge. It’s DCC fitted (with sound), so you’re not starting from scratch on the digital side—Hornby positions it as one of the DCC-fitted options alongside other categories like DCC-ready and analogue.
From a modelling perspective, it’s described as finely detailed, and the A4 lineage is referenced as having a more streamlined steam circuit and improved efficiency in the real thing—so even if you’re not a history buff, it gives the model a clear “why it looks like this” story.

The essentials for DCC and sound
If you’re buying specifically for digital control and sound, this is the straightforward route: the model is DCC fitted and comes with sound. That reduces the amount of guesswork compared with models that are only DCC-ready.
That said, it’s still worth checking what your overall setup expects before you commit. “DCC fitted” generally implies it’s intended to be used within a DCC environment, so if your current train set is analogue-only, you may find it doesn’t suit how you currently operate. Also, sound is great when it matches your play style—if you’re trying to keep noise to a minimum, you’ll want to consider whether sound is something you actually want on a regular basis.
Where it shines in everyday use
A practical way to think about this model is as a “main line performer” for a steam-focused session. Imagine pulling it out of the box, running a short loop with a couple of wagons, and letting the sound and the smooth-running design do the heavy lifting for the atmosphere. Even without getting technical, the idea is that it should feel dependable in day-to-day operation rather than something fragile that you only bring out occasionally.


It also fits well if you like the idea of era-specific layouts. Since this is positioned as Era 3 and tied to the LNER and the ‘Big Four’ grouping, it makes more sense when you’re curating your fleet around that timeframe.

What to consider before buying
There are a couple of sensible checks that can save disappointment.
First, make sure you’re definitely in OO gauge territory. The product is described as an OO gauge model train, so track compatibility should be aligned with standard Hornby 00 gauge arrangements (the description mentions compatibility with standard Hornby tracks in general, but it’s still your responsibility to match your existing setup).
Second, DCC fitted with sound is a commitment. If your train set is not set up for DCC operation, or if you’re still deciding how you want to control your locomotives, you might find this is more than you need.
Who it’s for—and who may want to skip it
It’s a good fit if you’re building an OO gauge train set for adults or a train set with a more serious “operating” feel, and you want a steam locomotive with DCC control and sound included.

It may not be a great match if you’re purely running analogue, you’re noise-sensitive, or you’re buying mainly for display with no plan to operate in a DCC-friendly setup. In those cases, it can feel like you’re paying for features you won’t use.

Final verdict


It makes sense if you want a Hornby OO gauge steam locomotive that’s DCC fitted and includes sound, and you like the specific subject of the LNER A4 ‘Mallard’ in an Era 3 setting. It’s the sort of model that should add character to regular running sessions rather than only working as a shelf piece.
You may want to skip it if your layout is analogue-only, if you don’t want onboard sound as part of your routine, or if you’re not sure how you’ll control a DCC-fitted locomotive once it’s in your set.
