Yet another destination is in the works for Europe's growing network of overnight sleeper trains, which have had a strong revival after years of decline and discontinuation.
This time, it's Brussels working with Sweden on a plan to extend an already-proposed Copenhagen/Malmo-to-Cologne route on to Brussels, where it could connect to a variety of high-speed trains, including the Eurostar to London.
While Sweden and Belgium are enthusiastic about a possible 2022 start, there's one big bug in the works. Germany, which had originally been interested in the Cologne route, has now lost interest and hasn't committed to issuing the required permission for the train to operate. Negotiations with Germany have not been scheduled.
