However, step-two was taken on , whereby DB Autozug GmbH now operates only non-smoker trains. This is in line with obligations written into German law for the protection of non-smokers (BNichtrSchG) which imposed a general ban on smoking in all federal buildings, on public transport vehicles and long-distance trains.

DB Autozug GmbH is actively contributing to a cleaner environment and promoting public health, whilst increasing passenger comfort and customer satisfaction. In supporting this legislation DB Autozug GmbH has helped to promote good health and satisfy the wishes expressed by many customers for non-smoker trains. The DB Autozug team anticipates that smokers will accept the enforcement of this regulation generously as a necessary move to protect the health of all passengers.
