In view of a warning strike announced for Wednesday, Hamburger Hochbahn does not expect to be able to start bus and subway operations.
"We have to assume that the subways and buses of the Hochbahn will not run on Wednesday," said Hochbahn spokesman Christoph Kreienbaum on Tuesday.
The company will decide to what extent operating services are possible at all during the strike.
Hamburg - The Verdi trade union has called on Hochbahn employees to stop working from Wednesday morning at 3 a.m. to Thursday morning at 3 a.m. in order to emphasize their demands in collective bargaining.
The next round of negotiations is scheduled for Thursday.
The most important goal is reliable operation, which hardly seems possible in view of the announced strike, said the elevated railway.
This would be associated with a high safety risk if passengers pushed into overcrowded vehicles or onto platforms with the hope of a supposed transport offer.
Even a possible emergency timetable would not change anything, but rather increase the risks.
"Plannability and safety for the passengers have priority here," it said.
If they cannot do without their trip that day, passengers should switch to the S-Bahn and bus lines of the Hamburg-Holstein transport company (VHH) if possible.
Both companies are not affected by the strikes.
The hvv app and hvv.de provide information on which hvv lines are running.
From now on, Hochbahn will inform passengers via announcements, advertisements on destination displays, the hvv app and social media channels.
