To get across from the train from Gatwick to the Walton-on-Thames train
will
involve crossing to another platform, but the main problem you will find
is
the train to Walton on Thames. The trains on this service do not have
heavy
luggage racks, so the only space for them will be in the seat bays, or the
aisle. Again if travelling mid-week, the train to Walton-on-Thames will
probably be very full during rush hour. However, a Taxi would prove to be
quite expensive from Clapham Junction.

Crossing platforms *shouldn't* be too much of a problem. The Southern
service from Gatwick (www.southernrailway.com) will normally arrive at
platform 12, whilst the South West Trains stopping services to
Walton-on-Thames (www.swtrains.co.uk) usually leave from platform 11, which
is the other face of the same platform.

As mentioned, the trains get very full during the rush hours (particularly
between 16:30 and 19:00) and the OP would be advised to avoid that time.
However, out of the peak time there is usually plenty of room for stowing
luggage in the seating bays or by the doors.
