Conclusions by PTB
19
• Local train traffic (passenfers) is compatible, provided
adequate train technology is used
• Train-free time slots of 30 minutes have to be kept during the
working day
• An increase of the speed of cargo-trains is unacceptable.
• We are willing to re-evaluate the situation after a refurbishment
of the tracks and the (cargo-)trains.
