"We deeply regret the decision of these exhibitors, while at the same time we respect their wishes in light of current developments," says Matthias Steckmann, director of Messe Berlin. "With exhibitors from 18 countries registered to take part, plus an outstanding supporting programme, the signs were already good for the new trade fair this year. We will continue along this path in our preparations for Public Transport & Interiors 2013."

Messe Berlin also organises InnoTrans at its exhibition centre in Berlin. The bi-annual event is the largest railway exhibition in the world, attracting 2242 exhibitors and 106,000 visitors last September.
