The Mauerfall-Spezial, or “Wall-fall special,” can be purchased beginning on November 9 at 6:57 pm until 3 am the following day, the company said.
The timing mirrors the day and time of an East German press conference that announced the immediate lifting of travel restrictions for the country's residents. The Berlin Wall fell hours later, speeding the collapse of the communist regime and German reunification a year later.
The offer, available online and select ticket offices, is valid for travel on the 20 days between November 12 and December 1, Deutsche Bahn said.
No exchanges or refunds will be allowed, and tickets are limited to available space on trains.
