| An Intercity 125 has ploughed into a freight train in west London, killing six and injuring more than 150. British Transport Police say they have arrested the driver of the Swansea-Paddington service to question him in connection with manslaughter charges. The crash - which passengers said occurred with no warning - happened at 1315 BST near Southall station. Three inquiries have been launched - all focusing on whether the passenger express passed a signal at red or was mistakenly shown a green light. It is believed the 1032 to Paddington was travelling close to the maximum speed on the Southall approach of 125mph (201 kmh) as it hit the empty goods train being shunted across the main line. |
