I can NOT recommend this railroad. The curvature of the curves is a different than that of the switch. To compensate for the different curvature, rails with the same curvature of the soft case. However, these, with the last 3 digits of a 6-digit number, barely visibly marked under the rail. So instead of 243 007 is there at the end of the 224th After I called Marklin and I've had to explain how I, that is a product for 3-6 year-olds, can build together, I still get a little Kataog, is in the recorded exactly how I can lock out the rails , The numbers are, unfortunately, still others as the ones I have. Also one took any imagination or creativity. In the end you have to probably exactly the assembly instructions (given circles, ovals, turnout gear, etc.) hold or worser because the building is always a small gap remains at a point where the trains derail like. But what children like to put up with a catalog numbers back and begin to plan to build? We will not buy these tracks again. Since it has brought Santa Claus, we wanted to not send back. But they are a real Fechheit. Even if they were reasonable, but I expect that they at a company like Marklin, work.
