English Speaking Train Travel

I am planning a self guided trip to Switzerland. My husband and I only speak English. Will we have difficulty checking train schedules, knowing when and where to change trains, etc. Are signs also in English? Thanks for any advice.

You will have no problems. Virtually everyone associated with the transport and hospitality trades speaks English and all the signs are in English as well. As a country with significant tourist trade you will find people to be very helpful and responsive.
