Hello bmaccc1
If your parents do decide to opt for the Glacier Express and the Bernina Express, follow Anna’s advice.
But I have an alternative plan.
Introduction
I am in my mid-seventies and have been visiting Switzerland regularly ever since 1971. I am a British, and a Public Transport enthusiast.
I am assuming that your parents eventual destination when ‘they venture into Italy’ is Milan.
This journey will involve four stages. It is a very good idea to split the journey overnight in St Moritz.
The itinerary I am about to suggest will NOT use either the Glacier Express or the Bernina Express.
But the journey I am proposing will use the same railways as those trains. The scenery will be the same.
On day one your parents can take a lunch break in Chur. On day two it will be at Tirano.
There will be no seat reservations. That means no reservation fees. That also means (and this is very important) your parents pick their seats on the day of travel.
On all four legs of this journey there is a preferred side of the train on which they will want to sit.
To secure seats on the best side of the train, your parents should be on the departure platform 15 minutes before the scheduled departure. At Zurich, St Moritz and Tirano, it is better to be at the front of the train. At Chur they want to be at the BACK, though note that the rearmost carriages on the Chur-St Moritz train will be first class.
Of the total of six stations involved in this trip, only Chur is a through station where the platforms are reached through a subway. All the others, including Milano Centrale are dead end terminal stations. At Tirano there are separate Swiss and Italian stations, but they are next door to each other.
On all four legs regular trains run hourly. (More frequent Zurich to Chur.)
Note that Swiss Railways nowadays give almost all their trains route numbers, as though they were buses!
Zurich to Chur
Swiss Federal Railways (SBB) run hourly fast trains (route number IC3) from Zurich to Chur, departing at 38 minutes past each hour. (These trains usually come in from Basel, arriving Zurich at 26 past the hour.) The journey will take 74 minutes.
Your parents should sit on the LEFT in the direction of travel for great views over first Lake Zurich, and then a bit later over the truly delightful Walensee lake.
I cannot be sure of this, but I think the departures at 09 38 and 10 38 will be double-decks, so if your parents can get upstairs, they should travel on the top deck. Note that the stairs are much easier to climb than on a double-deck bus. And the train will not be in motion.
When your parents get to Chur, they do not rush for the next train to St Moritz. They go for refreshment!
(There are additional fast trains from Zurich to Chur leaving at 08 07, 10 07. The 08 07 is probably a single deck. The 10 07 will definitely be single deck.)
Chur to St Moritz
Rhaetian Railways (RhB) run trains numbered IR38 every hour from Chur to St Moritz. These trains depart from platform ten at 58 minutes past each hour. The journey takes one hour and 55 minutes.
Your parents should aim to be at platform ten by about 40 past the hour, and to be comfortably seated by 52 past the hour. Why 52? Because that is when the fast IC3 from Zurich arrives!
They will want to sit on the RIGHT in the direction of travel. (On leaving Chur, the IR38 passes directly underneath the bus station built on top of the train station.)
St Moritz to Tirano.
Rhaetian Railways (RhB) run trains departing at 48 minutes past each hour.
Your parents should get to the station by about 30 past the hour, and will want to be at the FRONT of the train, sitting on the right-hand side in the direction of travel.
The trains leaving at 07 48, 09 48 and so on are slower trains, route number R19. The 07 48 reaches Tirano at 10 23 … and so on throughout the day.
The trains leaving at 08 48, 10 48 and so on are numbered RE9. They are a bit faster. The 08 48 reaches Tirano at 1100, and so on throughout the day.
Tirano to Milan
Italian Railways (FS) run trains hourly from Tirano to Milano Centrale departing at 08 minutes past each hour. The journey takes two hours and 32 minutes. Your parents will want to be at the front of the train, sitting on the right in the direction of travel. They will get splendid views over Lake Como.
?Swiss Travel Pass? ?Interrail Global Pass? ?Eurail Global Pass?
If your parents are doing a lot of travelling within Switzerland, then they should consider investing in a Swiss Travel Pass, valid on all modes of public transport.
If this holiday involves travelling by train in more than one European country (I suspect that is the case) then, if resident within (geographical) Europe they should consider investing in Global Interrails. If resident outside Europe they should consider Global Eurails.
Kind regards
