Hello pratikchaudhari
Thanks for your request.
No. There is no baggage limit on the train. However, not every train has large area of luggage racks. Especially narrow and with little space are the EC and IC during rush hours.
I would like to recommend you our comfortable luggage service, which will transport your luggage for you. You can find more information here: sbb.ch/en/station-services
I wish you a nice day.
Kind regards, ZoeS
