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.
