Just wanted to know if there was any way of differentiating between the e300 and e320 Eurostar trains? I need to make a last minute trip to Brussels in 2 weeks and am not the greatest of fans of the seats on the e300 (Class 373) so if there was any way of knowing which service is diagrammed for the newer trains that would be great. I've already looked but I can't tell the difference between the trains at all.
