Both new systems, the 400 with four lanes and the 600 with six lanes are, as the 300, module systems. The difference to the 300 is the rail shape. With the 400 and the 600 it is possible, for the first time, to build a wooden track the same way as you would build a plastic track, in always changing layouts. No special parts are needed to finish a track. But with all existing parts, fitting into each other, thus resulting in a multitude of attractive tracks.

The ramps are an additional plus, they allow to build lower crossings as well as elevated crossings.

The race track libraries of the 400 and 600 contain, from the very beginning, a huge amount of curve radiuses with opening and closing curves. To be sure, we will continually extent our offer of track sections, the same way we do already with the 300. The extendibility of module systems is one of their mayor advantages.

The following examples are all build with the same "small" set. But a lot more race track layouts are possible with the modules of the sample set. The system fits easily into different spaces without any problem. And inspires to always new race tracks. You can download the sample with all required space details as PDF here.

Are you eager to play with the system? We have a PDF with all available track parts, inclusive the details of the radiuses with the ratio of 1:10. To download please click here.

As more different curve radiuses a system has, as more fun it is playing it. With the seven different curve modules, of the two systems, you can design a diversity of many, many curves. Here is a still incomplete selection of potential 180-degree-curves. To enlarge click here.).

Would you like to design a six lane track online? Than continue here to the 600.

Or would you like to design a four lane track online? Than continue here to the 400.

You are also able to design your desired race track offline. Just download the appropriate data file, unpack the file and just start. For a PC this way and for a Mac here.

Here the same for the 600: Download the appropriate data file, logout, unpack the file and just start. For a PC this way and for a Mac here.

400 and 600 are available as kit and as ready to race (rtr). To be able to submit you an offer, we asked you kindly, to design your desired race track (see above). With the screen shot and all the details, if kit or rtr, we are able to calculate. You can contact us here: Fax 0049 221 560 45 55 and 400and600(at)slotfire.de.
