Bereaved families marked 25 years since the Ladbroke Grove rail disaster on Saturday, 5 October, by laying floral tributes at the memorial.
Thirty-one people died and more than 220 were injured when a rush-hour train collided almost head-on with a high-speed train around two miles from Paddington station in west London just after 8am on 5 October 1999.
An inquiry revealed that the Thames service travelling from Paddington to Bedwyn in Wiltshire had gone through a red signal before crashing into the London-bound high-speed First Great Western train.
The grey memorial stone was surrounded by bouquets of fresh flowers and lit candles, with a plush toy laid down, during a wreath-laying ceremony.
