Quintinshill: Britain's worst rail disaster marked

The centenary of Britain's worst rail disaster is being marked.

More than 200 people died at Quintinshill, near Gretna, on 22 May 1915.

Most were soldiers, from Leith, who had been travelling on a troop train on their way to the front line at Gallipoli.
