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.

Single Track vs Double Track

Feature Single Track Double Track
Internal Width 34mm 69mm
Overall Width 37mm 73.5mm
Walls 2 (left & right) 3 (left, centre & right)
Centre Dividing Wall ✓ Full height, riveted both sides
Track Bed Strips 1 x 14mm 2 x 14mm
One Piece? ✓ No aligning needed

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.

Available Radii

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.

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.

Matching Stone Bridge Pillars

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.

How Many Do I Need?

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.

Finishing Tips

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.
