The Paris-Berlin night train was relaunched with great fanfare by the government last December. Three round trips per week initially, before a daily connection in October.
Tickets went on sale at the beginning of April for May and June, but not for all trains. Between May 11 and July 6, two weekly round trips between Paris and Berlin are no longer even mentioned on the ÖBB journey planning tool. Only the weekend round trip remains, departing on Friday evening from Berlin and Saturday evening from Paris.
