FCO update there advice on luggage when travelling by train
16 Sep 2008
If you are travelling by overnight train and have the use of a sleeping compartment, store valuables in the container under the bed/seat.
Do not leave your sleeping compartment unoccupied as some compartments only have a simple lock on the sliding door. On some trains there may be an additional security device, which can be attached to the fitted handle/lock unit. There may also be a steel switch at head-height on the door panel which, when pulled down, prevents the closed door from being slid open.
When travelling by train do not agree to look after the luggage of a fellow traveller or allow it to be stored in your compartment.
