Bachmann Branchline is the benchmark for OO gauge model railways in the UK. Consistently producing highly detailed, DCC-ready locomotives at sensible prices, Bachmann has earned its place in layouts across the country — from compact shelf layouts to full club baseboards. Whether you're adding your first locomotive or expanding a growing fleet, here's our pick of the best Bachmann locomotives available in 2026.
Why Choose Bachmann?
Bachmann has been producing OO gauge models in the UK since 1989, and the Branchline range has matured into one of the most comprehensive model railway catalogues available. What sets Bachmann apart:
- DCC-ready as standard — nearly every current Bachmann locomotive ships with an 8-pin or 21-pin DCC socket, making decoder fitting straightforward. Many top-of-range models come DCC Sound fitted out of the box.
- Prototype accuracy — Bachmann invests heavily in research, producing models that serious modellers are happy to run alongside more expensive alternatives.
- Broad era coverage — from pre-nationalisation steam to current freight diesels, there's something for every British layout era.
- Competitive pricing — Bachmann consistently delivers more detail per pound than most rivals at the same price point.
If you're new to model railways and still deciding on scale, our complete model railway guide covers everything from choosing scale to planning your first layout.
Best Bachmann Locomotives 2026
1. Bachmann Class 37 — The Diesel Workhorse
The Class 37 is arguably Bachmann's most beloved diesel model, and the 2024–2026 revised tooling proves why. Introduced by British Railways in 1960, the Class 37 hauled everything from passenger expresses to heavy freight — and Bachmann's OO gauge version captures that purposeful, rugged character beautifully.
The current release features a split-chassis design, dual flywheel motor for smooth slow-speed running, directional lighting, and a 21-pin DCC socket. Multiple liveries are available — BR blue, Trainload Petroleum, EWS maroon, and Regional Railways green among them. If you want one diesel that works on a wide range of layout eras, the Class 37 is it.
2. Bachmann Class 08 Shunter — Essential for Any Goods Yard
No freight layout feels complete without a Class 08. Bachmann's OO gauge model of this ubiquitous 350hp shunter is finely detailed, runs on a compact chassis that handles tight curves well, and comes in a wide variety of liveries spanning BR green through to later privatisation schemes.
The Class 08 is particularly popular with modellers building pre-1990s layouts — it was the workhorse of virtually every BR goods yard and engine shed from the 1950s right through to the current era. Good value too, typically sitting at the more accessible end of the Bachmann price range.
3. Bachmann Class 66 — The Modern Era Freight Standard
If your layout depicts the modern era — post-1998 onwards — a Class 66 is almost obligatory. Introduced to British rails by English Welsh & Scottish Railway, the Class 66 became the dominant freight locomotive on the network almost overnight, and remains so today.
Bachmann's tooling is excellent: the characteristic nose profile is spot-on, the running quality is smooth and consistent, and DCC Sound versions with authentic Class 66 audio are available. DB Cargo, Freightliner, DRS, and GBRf liveries are all represented in the range. It's a sizeable model, so check minimum curve radius before ordering if your layout has tight bends.
4. Bachmann Class 158/159 DMU — The Modern Passenger Standard
For passenger working on a contemporary layout, Bachmann's Class 158 Express Sprinter and its Class 159 South West Trains variant are the go-to choices. These are multiple-unit sets (sold as powered car plus dummy trailer) that cover a huge range of current and recent passenger liveries — Northern Rail, ScotRail, East Midlands Railway, and more.
The models feature interior detail visible through the clear windows, directional lighting, and a DCC socket in the powered car. They run quietly and smoothly, and the two-car format keeps the purchase price manageable. Highly recommended for layouts depicting the 1990s through to today.
5. Bachmann Britannia Class 7MT — The Steam Showpiece
For steam modellers working on BR Standard era layouts (1950s–1960s), the Britannia Pacific is Bachmann's prestige offering. The 7MT was BR's own design, introduced in 1951, and examples hauled express passenger services across the network. Bachmann's OO gauge version features a coreless motor for near-silent slow-speed running, working inside valve gear, and superb cab and boiler detail.
The Britannia is a runner — not just a shelf queen. The chassis is stable, it handles gradients well, and the DCC Sound versions (featuring a convincing 7MT exhaust beat) are genuinely impressive. If you want one steam locomotive that impresses both as a model and as a performer, this is the one to buy.
DCC or Analogue?
Every locomotive listed above runs on conventional analogue DC straight out of the box. To run them on a DCC layout, you'll need to fit a decoder — the 21-pin socket on most current Bachmann models makes this a plug-and-fit operation, no soldering required. For DCC Sound, look for models pre-fitted at the factory (usually labelled 'DCC Sound' in the product listing) or source a sound decoder separately. Our DCC model railway systems collection covers decoders, controllers, and everything needed to go digital.
New Releases to Watch in 2026
Bachmann typically announces new toolings and limited-edition liveries through their annual catalogue. In 2026, watch for new Class 90 electric locomotive variants and expanded Class 158 livery options. Weathered versions — particularly the Class 37 and Class 66 — continue to sell quickly, so pre-ordering through the Bachmann Locomotives collection is the safest way to secure popular liveries before they sell out.
Bachmann vs Hornby: Which Should You Choose?
Both manufacturers produce excellent OO gauge locomotives, and most experienced modellers run both. Bachmann tends to have the edge on diesel and modern traction, while Hornby has traditionally dominated steam — though both ranges have narrowed that gap considerably in recent years. Our in-depth Hornby vs Bachmann comparison covers the detail if you're weighing up which manufacturer to invest in first.
Where to Start
If you're building a layout from scratch, it's worth looking at the model railway train sets — Bachmann produce several complete starter sets that include a locomotive, rolling stock, oval of track, and a controller. These give you everything to run trains on day one, and the locomotive from the set can be moved onto a more permanent layout later.

Final Thoughts
Bachmann's 2026 range is the strongest it's been in years. The Class 37, Class 66, and Britannia in particular represent outstanding value — accurate, well-engineered, and capable of running reliably on layouts of any size.
