CONTROL AND CERTIFICATION
Each Dotto production phase is subject to rigorous control
tests in order to assure high quality and safety standards,
in compliance with the strict regulations in force in Europe
and throughout the world.
The diesel, petrol, gas and electric engines are manufactured
in strict compliance with the environmental protection laws and
are distinguished by their particular noiselessless.
Testing of those trains, destined to public areas is carried
out according to directives of competent ministries, whilst as
far as private areas are concerned, a rigid internal protocol
is observed.
All Dotto products are tested and approved by the rigorous German
organization Tüv.
