Hello wyytamtravel
Welcome to the SBB Community.
We are a customer support forum run by volunteers.
Yes, but keep in mind that there is no same-day transfer. The later you check-in the luggage, the later it will be delivered to Montreux; transfer requires two days.

Very crucial to know as a travel guide: Swiss people like niceties; asking someone for help here, without greeting first, is considered unpolite and people usually unwilling to help or with little motivation only. You should remember this as a travel guide, as you will work closely with Swiss residents and you are dependent on them 🙂.
Kind regards,
Roland
