Yes. but there are many ways to get from Koeln airport to Nuremberg,
using combinations of ICE, IC, EC trains.
I am booking the most expensive option: ICE straight from Koeln Messe
to Nuremberg. Presumably if I miss this I will be able to get to
Nuremberg via one of the cheaper routes with no problems when I get my
ticket inspected.

Not sure whether routing via Köln Hbf is more expensive.
