Foundation for Permanent and Individually Landscaped TT Layouts
What is Tillig TT track without roadbed?
Tillig TT track without roadbed is known as the TT model-track system. The track has no permanently moulded ballast body. The rail profiles and sleepers are laid directly on a prepared track bed. Cork, sound insulation, ballast, trackside paths and embankments can therefore be designed to match the represented prototype.
The system belongs to the TT nominal size at a scale of 1:120. The model track gauge is 12 millimetres. The nickel-silver rail profiles are 2.07 millimetres high. The track uses the usual two-rail principle and can generally be used for analogue or digital train operation.
Model track is especially suitable for permanent home layouts, modules, sectional layouts, stations, hidden yards, branch lines and industrial connections. Fixed straights and curves simplify precisely repeatable geometry. Flexible track, by contrast, permits transition curves, free radii and flowing route alignments.
Wooden, concrete and steel sleepers permit different track appearances. Wooden sleepers suit many historical and modern layouts. Concrete sleepers often identify modernised main lines. Steel sleepers are suitable for distinctive older or regional track sections.
The system also includes connection track, isolation points, contact track, uncoupling track, crossings, several turnout geometries, individual rail profiles, sleeper strips, turnout drives and complete track packages. The range therefore extends from a small station to an extensive multi-track layout.
Flexible Track for Natural Routes
Flexible track permits smooth transition curves, freely selected radii and alignments that are less strictly tied to a fixed grid.
Individual Roadbed and Ballasting
The height, colour, width and weathering of the track formation can be adapted individually to a station, main line, branch line or industrial connection.
Track Planning with Coordinated Lengths and Angles
Selecting Radii, Partial Curves and Compensation Track Correctly
Tillig combines fixed curves with angles of 30, 15 and 7.5 degrees. Twelve 30-degree curves, 24 15-degree curves or 48 7.5-degree curves each form a complete circle. The technically possible radius should always be compared with the required minimum radius of the locomotives and vehicles being used.
| Geometry | Radius | Angle | Track Sections per Circle | Typical Application |
|---|---|---|---|---|
| R01 | 267 mm | 30° | 12 sections | Exceptionally compact alignment; check vehicle specifications carefully |
| R04 | 267 mm | 7.5° | 48 sections | Short compensation section for the smallest fixed radius |
| R11 | 310 mm | 30° | 12 sections | Compact inner circle and smaller TT layouts |
| R12 | 310 mm | 15° | 24 sections | Partial curve and geometric compensation |
| R14 | 310 mm | 7.5° | 48 sections | Fine angle correction within the R11 system |
| R21 | 353 mm | 30° | 12 sections | General-purpose outer parallel circle |
| R22 | 353 mm | 15° | 24 sections | Partial curve and connection to turnout geometry |
| R24 | 353 mm | 7.5° | 48 sections | Short compensation section within the R21 system |
| R31 | 396 mm | 30° | 12 sections | More generous visible routes and longer vehicles |
| R32 | 396 mm | 15° | 24 sections | Large partial curve and station approach |
| Flexible Track | Individual | Freely planned | According to the plan | Transition curves and individually flowing routes |
Do Not Confuse TT with H0m
TT standard gauge and H0m metre gauge both use a 12-millimetre model track gauge. TT represents standard gauge at a scale of 1:120, while H0m represents metre gauge at 1:87.
Analogue and Digital Connection Track
Different connection products are available for a prefabricated power feed. Analogue connection track 83143 and digital connection track 83149 must be selected according to their intended operating method.
Without Roadbed Does Not Mean Without a Substructure
A level and torsion-resistant track bed remains necessary. Sound insulation, track fixing, functional testing and final ballasting can then follow as required.

From the Track Plan to Reliable Operation
Planning and Laying Tillig TT Model Track Correctly
The advantages of model track are especially apparent when the track plan, substructure, turnout drives, power feeds and later landscaping are planned together. A careful test phase prevents faults in difficult-to-reach areas from becoming apparent only after ballasting.
Stations and Turnout Formations
Fixed straights, compensation pieces, EW1 to EW3 turnouts, curved turnouts, crossings and double slips permit compact or generous station approaches.
Visible Main and Branch Lines
Flexible track and larger radii create flowing routes. The selected sleeper type also determines the historical and regional character.
Hidden Yards and Concealed Areas
Concealed track must also be reliable, accessible and supplied with sufficient power. Maintenance openings are more important than an additional storage track which cannot later be reached.
Step 1
Match the Vehicles and Radii
Check the minimum radius of the longest locomotives and vehicles. Visible routes benefit from larger radii and smooth transition curves.
Step 2
Prepare the Substructure and Track Centre Line
The track bed, insulation and centre line must be level and accurately prepared. Unevenness must not be corrected by forcing the track into position.
Step 3
Plan the Electrical System and Drives
Power feeds, isolation points, feedback sections and turnout drives should be fully marked before the track is fixed permanently.
Step 4
Test and Then Add Ballast
Test every route using different vehicles. The track should be fixed and ballasted permanently only after reliable operation has been achieved.
Avoid Common Track-Construction Errors
- Forcing flexible track under tension into a tight curve
- Positioning both rail joints at exactly the same point in a curve
- Considering turnout drives only after completing the scenery
- Providing too few power feeds for a larger layout
- Allowing ballast adhesive to enter throw bars or point blades
- Building concealed track without access or derailment protection
Guidance for Flexible Track and Turnout Areas
Flexible track should be cut cleanly to length using suitable tools and fixed without tension. Adhesive and ballast must be used especially sparingly around point blades, frogs, throw bars and drives.
Answers About System and Product Selection
Frequently Asked Questions About Tillig TT Track Without Roadbed
These answers help with radii, flexible track, connection products, turnouts, sleeper types, transitions, multipacks and complete layout track sets.
What does Tillig TT model track without roadbed mean?
The rail profiles and sleepers have no integrated ballast bed. The track is laid on a prepared track bed and then insulated, fixed, weathered and ballasted as required.
Is Tillig TT model track suitable for digital operation?
Yes. The track can be used for analogue or digital operation. Connection track 83149 is intended for a prefabricated digital power feed. Connection track 83143 is designed for analogue operation.
Which fixed radii are available?
The principal fixed radii are 267, 310, 353 and 396 millimetres. Depending on the radius, curves with angles of 30, 15 or 7.5 degrees are available.
How many curved tracks are required for a circle?
Twelve pieces form a circle when using 30-degree curves. Twenty-four pieces are required at 15 degrees and 48 pieces at 7.5 degrees.
Which flexible track suits which route?
Products 83125 and 83495 have wooden sleepers. Product 83134 represents concrete sleepers and 83136 steel sleepers. Different route types and modernisation states can therefore be represented.
What is the difference between EW1, EW2 and EW3?
EW1 is intended for more compact track plans. EW2 and EW3 permit longer and more slender routes. EW3 has the smaller branch angle of twelve degrees.
Do Tillig model-track turnouts require a separate drive?
The drive for many individual turnouts is selected separately to suit the installation. Manual drives, side-mounted electric drives and motorised under-baseboard drive 86112 are available.
Can older Tillig standard track be connected?
Transition track 83132 is intended for connecting the former standard-track system to model track. Differences in rail height should not be corrected by forcibly bending the track.
What are isolation and interruption tracks used for?
They create electrically separated sections, for example switchable storage tracks, block sections or feedback areas. Depending on the product, one or both rails are isolated.
What are check-rail tracks used for?
Check rails increase the lateral guidance of wheelsets on bridges, tight sections or technically demanding areas. Products 83190 to 83194 permit double-sided and single-sided versions.
When is a multipack worthwhile?
Multipacks are useful when larger quantities of the same item are required for long routes, complete circles or several identical turnouts.
What do the named layout track sets contain?
The sets combine model-track products for a particular layout design. The main image shows the associated track plan. Buildings, vehicles and scenery are included only when this is stated expressly on the product page.
