Everything you need to know to start your first model railway
Published 12 March 2026
I'm going to let you in on a secret: every single person with a magnificent model railway layout started with absolutely no idea what they were doing. Every one of them. The bloke at the exhibition with the perfect ballasted track and the hand-built signal box? He once glued his first building together wonky and couldn't get his loco round a bend without derailing. We all start somewhere.
If you've been eyeing up model railways but feel overwhelmed by all the scales, jargon, and price tags — take a breath. It's much simpler than it looks. Let me walk you through it.
Scale is just how big your models are compared to the real thing. Pick the wrong one and you'll end up buying stuff that doesn't work together, so this matters. The good news is that for most people in the UK, the answer is pretty straightforward.
This is the big one. By far the most popular scale in Britain. Your models are 4mm to the foot and they run on 16.5mm track. Hornby, Bachmann, Dapol, Oxford Rail — they all make OO. That means a massive range of locos, coaches, wagons, buildings, and accessories. You'll never run out of things to buy. (Your wallet might have opinions about this.)
OO is a good balance between being big enough to see decent detail and small enough to fit a worthwhile layout into a spare room. It's the default choice for a reason.
Roughly half the size of OO. Runs on 9mm track. The big advantage? You can fit a much more ambitious layout into a small space. People have built proper N gauge layouts on bookshelves. Inside suitcases. I'm not making that up.
The trade-off is fiddliness. The models are tiny, and if you've got big fingers (or a heavy-handed approach), you might find them frustrating. Dapol, Graham Farish, and Revolution Trains are the main players in UK N gauge.
O gauge (1:43.5 in the UK) is the big stuff — gorgeous detail, but you'll need a serious amount of space. Z gauge (1:220) is absurdly small, desk-layout territory. There are others too, but honestly? If you're just starting out, go OO. You can always branch out later once you've caught the bug.
Starter sets are the easy button. One box: loco, some coaches or wagons, a loop of track, a controller, a power supply. Open it, clip the track together, plug it in, and you've got a running railway. Hornby and Bachmann both do a range of these, starting at about thirty quid for a basic set and going up past a hundred and fifty for the fancy DCC ones.
My advice? Go mid-range analogue for your first set. The cheapest ones can have ropey track and locos that stall on bends, which is discouraging. The mid-range sets run properly and you won't be tearing your hair out on day one. Skip DCC for now — you can upgrade later if you get serious. And pick a set with a loco you actually like. If you're mad about steam, get a steam set. If you think Class 66 diesels are the real deal, go diesel. You'll spend more time with it if you love what's running on the track.
A starter set gives you a loop of track. A layout gives you a world. This is where model railways stop being a toy and start being a hobby. And it's not as hard as you think.
You need something flat and sturdy. A sheet of 9mm or 12mm plywood on a frame of 2x1 softwood battens does the job nicely. Six feet by four feet is a popular size for OO — big enough for a decent track plan, small enough to fit in a spare room or the garage. If space is really tight, you can do a lot with a 4x2 foot board. Seriously — some of the best layouts I've seen at exhibitions are tiny.
Sketch it out on paper first. Trust me on this. Decide what you want: do you just want to watch trains going round (nothing wrong with that — it's therapeutic), or do you want stations and sidings for shunting? A simple oval with a couple of sidings is a brilliant starting point. There's free track planning software online if you want to get fancy, but pencil and paper works fine.
This is the single most important thing you'll do. If your track is wobbly, kinked, or has loose joints, your trains will derail constantly and you'll want to throw the whole lot out the window. Lay it flat. Pin it down or glue it. Make sure the joints are tight and aligned. Then test it with a loco before you do anything else. Fix problems now, not after you've covered everything in static grass.
Right, this is the fun part. Bare plywood with track on it looks rubbish, let's be honest. But a bit of paint, some scatter, and a few buildings later? Suddenly it's a place. You don't need to be artistic. Some of the best scenic techniques are basically just "spread glue and sprinkle stuff on it."
Paint your baseboard first — brown and green acrylic, nothing fancy. Then scatter materials: fine-textured coloured powders and fibres stuck down with PVA glue (the white stuff you used at school). Static grass applicators are a game-changer — they stand individual grass fibres upright and the result looks startlingly realistic. A pot of scatter costs a few quid and lasts ages.
You can buy ready-made trees, or twist some wire into an armature and cover it with scatter material. Hedgerows? Strips of rubberised horsehair (sounds weird, works brilliantly) coated with green scatter. Bushes from clumps of foam. Flowers from tiny dabs of coloured flock. None of this is difficult and the results are surprisingly convincing.
Metcalfe card kits are my go-to recommendation for beginners. They're cheap, they look great, and they go together without any specialist skills. Just score, fold, and glue. Bachmann Scenecraft and Hornby Skaledale do ready-made plastic buildings if you'd rather skip the building part entirely (no judgement). For stations, signal boxes, houses, engine sheds — the range available is enormous. You'll be spoilt for choice.
People think model railways are expensive. They can be, sure — the same way any hobby can be if you go mad. But they don't have to be. Here's how to keep it sensible.
My nephew is six and he's happy just watching trains go round and round. My dad is seventy-two and he's scratch-building a GWR engine shed from photographs. Same hobby, completely different experiences, both absolutely loving it.
Kids pick up practical skills: woodwork, basic electrics, painting. Adults get a creative outlet and something genuinely relaxing to do after work. And building a layout together — parent and child, grandparent and grandchild, mates at a club — is one of the best things about this hobby. You're making something together. That counts for a lot.
Stop overthinking it. You don't need the perfect space. You don't need a big budget. You don't need a plan. Buy a starter set, stick some track on a board, and run a train. That's it. Every modeller in the world started exactly there: one loco, one loop of track, and a daft grin on their face. The rest follows naturally.
