The Signal Box You've Always Wanted (But Didn't Know You Could Build)

Right, so here's the thing. This is rather a splendid little signal box, based on the larger of two that once stood at Spondon Junction. The Midland Railway built it, and it's the sort of structure that makes model railway layouts go from pleasant to properly magnificent. We've designed this as the extended version, which means it's ideal for substantial junctions or station entrances where you want something that actually commands attention.

Why Choose Our Signal Box Model

Gorgeously Detailed Interior: Comes with interior accessories so you can decorate the inside. It's the sort of thing that separates the casual enthusiast from the genuinely committed, if we're being honest.

Brick Foundation and All-Round Windows: Features a brick foundation with windows on all sides. It's rather fetching, actually, and the attention to detail is marvellous.

LED-Ready Design: Space for LED lighting has been thoughtfully included, so you can make the whole thing glow rather beautifully when the mood takes you.

Era 2 Through 11 Compatible: Works with UK model railway eras 2 through 11, so it fits rather nicely into most layouts.

Customisable Finish: Supplied as an unpainted 3D printed resin piece, ready for acrylic or enamel paints. You get to make it entirely your own, which is rather marvellous.

Product Details

What's Included: One unassembled, unpainted signal box model in resin. Windows require careful cutting from a separate transparent sheet (yes, there is a touch of effort involved, but that's part of the charm).

Assembly: Clearances have been included to aid assembly. Do read through the instructions and perform a dry assembly before gluing. We rather recommend this approach.

Preparation: May require some sanding and filling before painting. Think of it as giving the model a bit of polish before it becomes the showstopper it was meant to be.

Scale: TT 120 and 3mm scale.

Dispatch: Building orders are dispatched within 7 working days via Royal Mail to UK and overseas addresses.

Note: Detail may vary slightly from photographs depending on the size of building ordered. Rather like people, really, no two are exactly identical.

Warning: This is not a toy. Small parts included. For adult collectors aged 14 and above.

If questions arise or anything seems amiss, do get in touch. We're rather helpful about such things.

THE RATHER IMPORTANT BITS

This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.

SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.

Some are brilliant at international shipping, others prefer to keep things closer to home.

At checkout, you'll see exactly where this particular brand can send your goodies.

We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!


RETURNS

You have 14 days to return items.

Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!

We Have Lots More Like This.........

Hello, we are Sostter....

Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?

We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.

Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.

This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
