Individual Roadbed Design and Clear Track Geometry
What is PIKO A-Track without roadbed?
PIKO A-Track is an H0 two-rail track system without a permanently moulded ballast roadbed. Rails and sleepers are laid on a prepared route. Sound insulation, the ballast bed, trackside paths and embankments can therefore be designed individually.
The system belongs to H0 gauge at a scale of 1:87 and has a model track gauge of 16.5 millimetres. The rails are made from nickel silver and can be used on analogue or digital two-rail layouts.
The geometry is based on a basic module measuring approximately 470 millimetres. G239 and G231 straight track combine to form this length, simplifying parallel station tracks and turnout formations.
The 940-millimetre flexible track corresponds to approximately twice the module length. It permits free radii, transition curves, flowing routes and individually cut straight sections.
In addition to the classic wooden sleeper track, flexible track and left- and right-hand turnouts with concrete sleepers are available. These can be used to represent modern main lines and station areas.
Modern Concrete Sleeper Track
Flexible track and 15-degree turnouts with concrete sleepers complement modern main lines.
Flexible Track for Free Radii
The long flexible track permits transition curves and freely flowing track alignments.
Four Basic Radii and a Turnout Reverse Curve
Compare PIKO A-Track Radii and Geometry
Twelve 30-degree curves form a complete circle. The short 7.5-degree curves permit finer angle corrections. The R9 curve forms the reverse curve for standard 15-degree turnouts.
| Geometry | Radius | Angle | Products | Typical Application |
|---|---|---|---|---|
| R1 | 360 mm | 30° or 7.5° | 55211, 55251 | Compact inner circle |
| R2 | 421.88 mm | 30° or 7.5° | 55212, 55252 | Outer parallel circle |
| R3 | 483.75 mm | 30° | 55213 | Visible routes and larger vehicles |
| R4 | 545.63 mm | 30° | 55214 | Generous outer circle |
| R9 | 907.97 mm | 15° | 55219 | Reverse curve for standard turnouts |
| Standard Turnout | 907.97 mm | 15° | 55220, 55221 | Stations, sidings and passing loops |
| Flexible Track | Individual | Freely planned | 55209, 55150 | Transition curves and freely planned routes |
470-Millimetre Basic Module
G239 and G231 together form the basic system length for parallel track connections.
Observe Vehicle Radii
Long locomotives, coaches and multiple units benefit from R3 or R4 on visible routes.
Without Roadbed Does Not Mean Without a Substructure
A level route, sound insulation and a properly constructed ballast bed remain necessary.

From the Track Plan to an Individually Ballasted Layout
Planning and Laying PIKO A-Track Correctly
The advantages of track without roadbed become particularly apparent when the substructure, flexible track, radii, turnout drives, power feeds and ballasting are planned together.
Stations and Turnout Formations
Straight track, R9 reverse curves, standard turnouts, curved turnouts and crossings permit versatile station layouts.
Visible Main and Branch Lines
Flexible track and larger radii create flowing, prototypical routes.
Modern Main Lines
Concrete sleeper flexible track and matching turnouts identify modernised routes.
Step 1
Match Vehicles and Radii
Check the minimum radius of the longest locomotives and coaches.
Step 2
Prepare the Substructure and Track Centreline
The route, sound insulation and track centreline must be level and free from twisting.
Step 3
Plan Electrics and Drives
Power feeds, isolation points and underfloor drives should be installed before final track fixing.
Step 4
Test First, Then Add Ballast
Test every route using different vehicles before applying ballast adhesive.
Avoid Common Track-Construction Errors
- Forcing flexible track under tension into tight curves
- Compensating for an uneven base by distorting the track
- Using R1 without checking long vehicles
- Providing too few power feeds
- Allowing ballast adhesive to enter point blades
- Installing underfloor drives without maintenance access
Guidance About Connection Clip 55270
The connection clip includes interference suppression and is intended for analogue layouts. The electrical equipment must match the control system being used.
