Without seeing the actual brochure you are referring to, it's not easy to understand exactly what is confusing you.
The Landwasser Viaduct is simply a (rather spectacular) feature of the journey on the Glacier Express route between Tiefencastel and Filisur. The view doesn't last very long, but it is impressive. The most common publicity photos for the Glacier Express feature a view of that viaduct, so that might explain why the brochure draws attention to it.
Reichenau-Tamins is a station the Glacier Express travels through twice between Zermatt and St Moritz, but it doesn't stop there. The first time it goes through Reichenau-Tamins is on the way from Zermatt to Chur, then from Chur it retraces its tracks to Reichenau-Tamins before turning south to head for St Moritz. A similar thing happens going in the opposite direction.
If you are travelling on the "official" Glacier Express train (and not on local trains over the same route), it is a direct service, with no changes of train, between Zermatt and St Moritz or vice versa. Just sit down, look out the panoramic window and enjoy the ride!
As Arno said, please post specific details if you need more help. Posting in a new thread would be best :-)
