That's an interesting question about the carbon emissions - I think I'll need to dig into that for a while, and make it a follow-up post. Based on some quick digging online (e.g. here), planes generate 0.09429 kg CO2/km and trains generate 0.01502 kg CO2/km. So, that means that 1 km by plane ~= 6.2 km by train. I'm certainly going further by train, but probably not that much further. The other aspect is that electric trains could theoretically use alternate energy sources, e.g. solar power, whereas planes have to use oil.

As for longer stops, the main issue is annual leave. (I've booked 8 days off for this, and another 10 days for my 4 LARP events.) That said, if I left London on Sunday rather than Monday then I could spend a bit longer in Brussels, so I'll have a look and see whether it would be feasible to change my ticket.

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!
