There are a couple more complicating factors:

1. Planes also emit water vapour in the stratosphere, which is a GHG. Hence their CO2eq emissions are around twice their raw CO2 emissions.
2. Not all trains are equal - high-speed trains use significantly more energy per passenger-mile than slow trains.

It's not clear to me whether the site you link to takes point 1 into account, but if it uses Eurostar figures for the trains then it's probably overestimating the emissions of your train journey. I'd thought high-speed train emissions were roughly on a par with planes' - perhaps the difference is short-haul versus long-haul flying? Short-haul flights have much higher emissions per passenger-mile, as much of the energy is used in takeoff and landing.

And don't forget the ferries!
