Realistic Code 83 Track with Flexible Roadbed
What is ROCO LINE with roadbed?
ROCO LINE with roadbed is an H0 two-rail track system with a preassembled ballast body. The rail profile, sleepers and roadbed form one coordinated 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 rail profile is 2.1 millimetres high and approximately corresponds to Code 83.
Standard straight G1 is 230 millimetres long. G½ measures 115 millimetres and G¼ measures 57.5 millimetres. The long G4 straight reaches 920 millimetres and corresponds to four standard straights.
The fixed curve radii range from the compact R2 at 358 millimetres to the slender R10 at 888 millimetres. R9 and R10 each have an angle of 15 degrees.
The turnouts are initially operated manually. Universal roadbed turnout drive 42620 or digital DCC turnout drive 42624 can be added for electric operation.
Realistic Code 83 Profile
The 2.1-millimetre profile is lower and more prototypical than traditional Code 100 systems.
Retrofittable Turnout Drives
Turnouts can initially be used manually and later equipped for electric or digital operation.
Straights, Parallel Radii and Slender Turnouts
ROCO LINE Radii and Turnout Geometry
Twelve 30-degree curves or twenty-four 15-degree curves form a complete circle. R9 and R10 can also be used as reverse curves for turnout and crossing connections.
| Geometry | Radius or Length | Angle | Product | Typical Application |
|---|---|---|---|---|
| G1 | 230 mm | – | 42510 | Standard straight and basic grid |
| G½ | 115 mm | – | 42512, 42521 | Half standard straight and feeder track |
| G¼ | 57.5 mm | – | 42513 | Short geometric compensation |
| R2 | 358 mm | 30° | 42522 | Compact inner circle |
| R3 | 419.6 mm | 30° | 42523 | Second parallel circle |
| R4 | 481.2 mm | 30° | 42524 | Visible routes and larger vehicles |
| R5 | 542.8 mm | 30° | 42525 | Generous outer circle |
| R6 | 604.4 mm | 30° | 42526 | Long vehicles and main lines |
| R9 | 826.4 mm | 15° | 42527 | Partial curve and turnout geometry |
| R10 | 888 mm | 15° | 42528 | Reverse curve for 15-degree turnouts |
| W15 | 230 mm / radius 873.5 mm | 15° | 42534, 42535 | Stations and sidings |
| W10 | 345 mm / radius 1,946 mm | 10° | 42582, 42583 | Slender station approach |
| DKW15 | 230 mm / radius 1,050 mm | 15° | 42595 | Compact double track connection |

From a Track Set to a Permanently Reliable Layout
Planning ROCO LINE with Roadbed Correctly
The roadbed, radii, turnout drives, power supply and maintenance access should be planned together before the track is permanently secured.
Temporary Construction
The preassembled roadbed is suitable for test layouts and track plans that are changed regularly.
Permanent Model Railway Layout
The roadbed edges can be painted and integrated into the surrounding scenery.
Station and Turnout Formation
Turnouts with angles of 10 and 15 degrees permit compact or generous station approaches.
Step 1
Match Vehicles and Radii
Check the minimum radius of the longest locomotives, coaches and multiple units.
Step 2
Plan Straights and Reverse Curves
Use matching system lengths instead of connecting track under tension.
Step 3
Define the Drives and Electrics
Decide at an early stage between manual, electric and digital turnout control.
Step 4
Test First, Then Secure the Track
Test every route before final fixing and scenery work.
Avoid Common Errors
- Using R2 without testing long vehicles
- Connecting track at an angle or only partially
- Using feeder track 42521 on a digital layout
- Selecting turnout drives only after layout construction
- Distorting the flexible roadbed with screws
- Building concealed track without maintenance access
Guidance About Double-Slip Turnout 42595
The double-slip turnout requires two suitable turnout drives for complete electric operation.
