A-Track Geometry with a Permanent Ballast Body
What is PIKO A-Track with roadbed?
PIKO A-Track with roadbed combines the rail profile, sleepers and a moulded plastic ballast roadbed to form a stable track element.
The system belongs to H0 gauge at a scale of 1:87 and has a model track gauge of 16.5 millimetres. The track can be used on analogue or digital two-rail layouts.
The integrated roadbed simplifies rapid construction and creates a complete track appearance without requiring additional ballasting.
The basic geometry uses long and short straights, several fixed radii and different turnout designs. Connection track 55406 is prepared to accept suitable connection clips.
Product 55434 connects A-Track with roadbed to PIKO A-Track without roadbed. Visible and concealed layout sections can therefore use different track constructions.
Precisely Fitting Connections
The track can be assembled into straights, circles, parallel routes and stations.
Transition to Track Without Roadbed
Transition track 55434 connects both PIKO A-Track versions.
Basic Radii and Turnout Reverse Curve
Compare PIKO A-Track Radii
The 30-degree curves verified at Modellbahnshop cover R1 to R4. The R9 curve is used as the reverse curve for standard left- and right-hand turnouts.
| Geometry | Radius | Angle | Product | Typical Application |
|---|---|---|---|---|
| R1 | 360 mm | 30° | 55411 | Compact inner circle |
| R2 | Approx. 422 mm | 30° | 55412 | Outer parallel circle |
| R3 | Approx. 484 mm | 30° | 55413 | Visible routes |
| R4 | Approx. 546 mm | 30° | 55414 | Generous outer circle |
| R9 | Approx. 908 mm | 15° | 55419 | Reverse curve for standard turnouts |
| Standard Turnout | Approx. 908 mm | 15° | 55420, 55421 | Stations and sidings |
| Curved Turnout | Curved route | System geometry | 55422, 55423 | Space-saving junction within a curve |
Observe Vehicle Radii
Long locomotives, passenger coaches and multiple units benefit from R3 and R4.
Combine G239 and G231
Together, the two long straights form a basic module measuring approximately 470 millimetres.
Use the Connection Track
Product 55406 includes a prepared mounting point for suitable connection clips.

From the First Track Oval to a Complete Layout
Planning PIKO A-Track with Roadbed Correctly
Temporary Layout
The stable track is suitable for test layouts, seasonal layouts and adjustable track plans.
Permanent Model Railway Layout
The track can be secured permanently and integrated into the scenery along the roadbed edges.
Station and Shunting Area
Turnouts, curved turnouts, a double-slip turnout and a wye turnout provide varied routes.
Step 1
Match Vehicles and Radii
Check the minimum radius of the longest vehicles.
Step 2
Close the Track Plan Geometrically
Use matching straights and reverse curves instead of connecting track under tension.
Step 3
Prepare Electrics and Drives
Test the connection track and turnout drives before securing the track permanently.
Step 4
Test First, Then Secure the Track
Test every route using different locomotives and coaches.
Avoid Common Errors
- Connecting track sections at an angle or incompletely
- Forcing unsuitable lengths together
- Using R1 without checking long vehicles
- Providing too few power feeds
- Installing turnout drives without maintenance access
- Distorting the roadbed by overtightening screws
Guidance About the Analogue Connection Clip
Connection clip 55270 includes interference suppression and is intended for analogue applications.
