Moreover, the model consists of modules can be expanded almost without limit except for the available space is also dynamic since it is well designed if the union between them including track gauges can be interchangeable with what we have a model that changes and we do not get bored with the same tendency as always.

Another advantage is that we can share it with others with similar lines, for which it is enough to agree with the joints of the boards.

As far as modules usually varies from 0.25 X 0.60mts. to 0.80 X 1.80Mts. tended to suit your requirements and can be straight or L for the case of curves which is usually what you need more space.

In the case of the union of the modules what must be taken into account is that the faces to be joined are completely smooth and flat to avoid bad joints.
On the other hand, the path will be placed flush with the front of the union or its defect sticking out of it and using the junction front will cut it to the reason of it.
After cutting and attaching the via will be made with matrix file a file of the inner side of the rail as a wedge to avoid derailments.
Union details are attached.
