>> I will be travelling from Interlaken to Geneva on 10th May with my husband and 20 month old toddler. I wanted to experience both the classic and the panoramic golden pass line trains.
Quite apart from the effects of the construction works, from 8 Jan to end July 2018, the Golden Pass Belle-Époque carriages are out of service, as they are being renovated. Trains with conventional wagons will operate on this sector at the scheduled times for the Belle-Époque train.
>> 7May- Luzern to Interlaken( stay at Grand Lindner hotel) ( i was considering a trip to Bern same day)
If you go to from Luzern to Interlaken via Bern, you will miss out on the very scenic Golden Pass sector between Luzern and Interlaken. If you have spare time in Interlaken after dropping your luggage off, I would recommend a trip to Mürren instead of Bern, following the circuit described in rockoyster's post of Jan 27, 2018 - 2:11 AM on the following page:
There is a picture with the route marked on this page:
>> The swiss timetable shows stops and changes at Spiez and Visp, one change for the bus , and a minimum 1 stop at Lausanne.
I'm a bit confused by this. Which trip/date is this in relation to? Visp is not on the Golden Pass route.
>> The SBB/ swiss travel timetables confuse me a bit as they show many connections as opposed to direct trains.
The Swiss Timetable will always show the fastest route by default. Sometimes changing more frequently gets you to your destination faster. However, in the list of connections that comes up in a search, you can select the one with the least number of connections if that is most important to you. Always check which platforms you arrive on and depart from, as you sometimes find a transfer simply means moving to the other side of the same platform.
>> What would you suggest the best for transfer between Luzern to Interlaken on 7 May at about 10 am?
There is a direct train from Luzern to Interlaken Ost at 10:06 on 7 May. This is part of the Golden Pass route, and very scenic.
Direct trains are standard between Luzern and Interlaken Ost, so direct trains should come up regardless of what day and time you search for. The exception would be if there is any construction on the route requiring a short bus-replacement sector - but that is not the case on 7 May 2018.
>> And for Interlaken to Geneve on 10th May?
If you don't want to travel via the Golden Pass route (Interlaken Ost-Zweisimmen-Montreux, then normal train to Geneva), there are services between Interlaken and Geneva with only one change (at Bern). This is less scenic, but if convenience is more important, this is an option.
If you take the 10:30 departure from Interlaken Ost to Bern, that train will have a family coach with play area (denoted in the timetable with the letters FA), and so will the next train you connect to in Bern (departing for Geneva at 11:34).
The family coach playground can be found upstairs in the carriage at either the very front or rear of the train (at the opposite end from the locomotive). It will be a second-class carriage. The lower deck has space for pushchairs.
There is more information here:
The change at Bern will be from Platform 4 to Platform 5. Lifts are located between Sectors C and D of the platforms (closer to D). The platform sector is denoted by square blue and white overhead signs on each platform - see picture here:
>> Im travelling with my husband and 20 month old toddler , 2 medium suitcases,a stroller, a diaper bag and a camera bag that need to change trains with us
Everyone has their own ways of organising such things, but if you can ensure that the diaper bag and camera bag are carried hands-free, that will make things easier.
The family coaches will have level entry from the platform, so you can push your toddler on in the stroller.
The train between Luzern and Interlaken has some doors that provide level entry from the platform - look for doors with a big wheelchair graphic on them, and you can push your toddler aboard on them as well (see attached photo).
