A beautician who survived a horror crash on the A40 said the driver swerved to avoid an animal.
Zamarod Arif, 26, said it felt like she was "in a Tsunami" when the 4x4 she was travelling in flipped onto a train track.
Zamarod's best friend Yagmur Ozden died in the smash, which took place near Park Royal tube station in west London on Monday.
