Quick and effective method of subsoil and railway substructure improvement by using explosive means (registered trade name: microblasting) allowes design and construct railways on lowered bearing soils (i.e. wetlands, marshlands, industrial by-products, municipal wastes, degraded antropogenic embankments). It is usefull and recommendable technology to construct new railways, modernization or maintenance and repairing of old ones...

We analyze the propagation of the waves generated by the rolling stock and the interaction of those waves on the medium and its surroundings. We use non-classical operational methods for monitoring construction of the railway infrastructure and for noise damping.
