For the ultimate flexibility, you can choose not to book at all. And it depends on where you want to get off if you don't want to go all the way to Tirano.
Bear in mind that the Bernina Express running all the way from Chur is a recent innovation.
It is important to understand the difference between the Bernina Railway and the Bernina Express. The Bernina Railway is the railway which runs St Moritz - Pontresina - Bernina Pass - Tirano, the only railway to cross the high Alps without a summit tunnel.
In recent years the RhB railway company decided to make it easier for tourists by making the ‘Bernina Express’ a through train all the way from Chur to Tirano, but only half the journey is on the actual Bernina Railway, the other half of the journey is on the Albula Railway en.wikipedia.org/wiki/Albula_Railway
The Bernina Railway is the (independent until 1947) railway built separately from the rest of the Rhatische Bahn railway. There are ordinary trains on this line and short distance Bernina Express services. en.wikipedia.org/wiki/Bernina_Railway
The following text was prepared in response to a question about northbound travel. Reverse the concept for a southbound trip:
Once you reach Pontresina you will have completed the journey on the Bernina Railway. As such you can then get any regular train from Pontresina to Chur, either via Samedan or via St Moritz. From St Moritz to Chur via Samedan is the UNESCO World Heritage Albula railway. It has express trains once per hour St Moritz – Chur, which have large windows and special photographer’s coaches so that when you get to the famous Landwasser viaduct at Filisur you get a good view
