We have cancelled the 2:30 train to Waterloo and we ask passengers who are

waiting for this train to go to platform 2 to take the 2:45 train instead. We will

accept any ticket types on the train. We expect the procession to be very crowded

and therefore any ticket holders can use the first class carriages.

We will sell refreshments on this train.
