Highly detailed curved girder bridge sections for N gauge model railways. Each section spans a 45-degree arc — use 8 sections for a complete circle, or fewer for any curve angle you need. Available in 11 standard radii — six metric sizes (230mm–365mm) plus all five Bachmann E-Z Track curves (11.25"–19") — and in both single and double track widths. Matching stone pillars also available — select from the options above.
Price is per section or per pillar. Select your product type and radius from the options above. Free UK delivery on all orders.

The double track version is a single piece — both tracks, all three walls, and the deck are printed together for perfect alignment every time. No need to buy two singles and try to line them up.
All radii measured at the centre of the bridge deck. Compatible with standard N gauge track radii, including the full Bachmann E-Z Track curve range.
| Radius | Centre Radius | Diameter | Arc Length per Section |

The EZ radii match Bachmann E-Z Track N scale curved sections exactly — pair the bridge with the matching track radius for a perfect fit. Need a different radius? We can produce custom radii to match any track — just message us.
Complete your viaduct with our matching stone pillars. Each pillar features coursed ashlar stonework on all four faces with individually modelled stone blocks, recessed mortar lines, a wider plinth base for stability, and an overhanging capping stone at the top for the bridge deck to sit on. The body has a subtle taper — wider at the base, narrower at the top — just like the real thing.
| Pillar | Top Width | Depth | Height | Fits | MPN |
|---|---|---|---|---|---|
| Single Track | 37mm | 14mm | 47mm | All single track bridges | 3DPP-SBP-ST |
| Double Track | 73.5mm | 14mm | 47mm | All double track bridges | 3DPP-SBP-DT |
Each pillar fits all 11 radii — select Stone Pillar (Single) or Stone Pillar (Double) from the product type options above. Place one pillar at each bridge joint for a full viaduct. The stone detail responds beautifully to washes and dry-brushing for a weathered finish.
| Scale | N Gauge — compatible with both UK 1:148 and international 1:160 layouts |
| Arc per Section | 45° (8 sections = full circle) |
| Radii Available | 11 — six metric (230, 265, 270, 300, 330, 365mm) plus five Bachmann E-Z Track (11.25", 12.5", 14", 15.5", 19") |
| Overall Height | 11.5mm (1.5mm deck + 10mm walls) |
| Deck Thickness | 1.5mm with open lattice girder, solid 14mm track beds with edge rivets, and riveted transverse beams |
| Wall Detail | Riveted plate girder — recessed panels with border rivets, horizontal divider, vertical ribs with double-row rivets, capped top rail with rivet detail on top |
| Material | PLA — lightweight, strong, takes paint well |
| Colour | Grey (as printed — primer recommended before painting) |
| MPN / Batch | 3DPP-CGB series (bridges) and 3DPP-SBP series (pillars) — unique MPN per variant |
| Compliance | EU-GPSR compliant — full product safety documentation included |
| Curve | Angle | Bridge Sections | Pillars |
|---|---|---|---|
| Gentle curve | 45° | 1 | 2 |
| Quarter turn | 90° | 2 | 3 |
| Half circle / return loop | 180° | 4 | 5 |
| Full circle | 360° | 8 | 8 |
Pillar count assumes one at each bridge joint plus one at each end. For a full circle the end pillars are shared, so 8 bridges need 8 pillars. Combine with our straight bridge sections for complex viaduct layouts.
Printed in grey PLA, ready for painting. A light coat of primer is recommended for the best finish. Takes acrylic and enamel model paints well. The hundreds of individual rivet heads, recessed panels, and beam edges respond brilliantly to dry-brushing and weathering powders — the surface detail gives washes and pigments something to grip onto for a truly realistic finish. The stone pillars are equally paint-friendly — a dark wash into the mortar lines followed by dry-brushing the stone faces brings them to life.
