London to Freiburg, anything we should know?

[jnjkerbin]

Ok, so we've booked some London Spezial Tickets (or whatever they've been renamed to) to travel from St Pancras to Freiburg in the next few weeks. Our itinerary is:

0858 St Pancras - Brussels Midi 1205
1425 Brussels Midi - Koln Hbf 1615

--Overnight Stop--

1053 Koln Hbf - Freiburg 1453 (Via Rhine Valley)

Return:

1157 Freiburg - Koln Hbf 1505 (Via HSL)

--Overnight Stop--

1143 Koln Hbf - Brussels Midi 1335
1456 Brussels Midi - St Pancras 1605

We've already done the Eurostar leg once before, but I was wondering if there was anything interesting/useful anyone could share about any aspect of the journey

Thanks in advance for any advice

Enjoy the slightly insane leaping over hills that the High Speed Line does between Siegburg/Bonn and Frankfurt Flughafen (better experienced at trains not calling at Montabaur and the other intermediate stop)

Obvious point: find seats on the LH side of the train south from Köln.
The train is formed of Swiss stock.

Oh Freiburg Germany not Freiburg/Fribourg Switzerland! Personally I find the latter more interesting, and the journey to and from.
