Belgium says late arrivals and delays on international trains crossing Belgium or serving Belgian cities are running late, and causing delays in the country's own train service.
In general, the international trains have priority on the domestic network, and when they fall off schedule, they delay Belgian trains on the lines, or cause them to be held for connections. Belgian railway operator SNCB says its on-time record dropped last year from 88.3% to 87.2%.
The worst offenders, apparently were German-operated trains. Only 6 out of 10 of Germany's ICE trains between Dusseldorf and Brussels operated on time last year. Eurostar, whose trains connect Brussels with London and Paris, is also a frequent offender.
