Just which decade are we talking about? And what do you classify as a major crash or significant loss of life? In the last ten years there has been only one accident where more than one passenger died, and that was due to a car driver deciding to park his car on a level crossing as a means to commit suicide and took 6 others with him. The MMA accident killed more in one hit than all our accidents combined in the last ten years,
Just look at the outstandingly low figures over the last ten years here:

And note that many of them are due to road vehicle incursions, not railway failings.
Not only that, the Herald of Free Enterprise was a long time ago and things have changed, and is about as relevant as citing the Titanic as an example of current safety culture!!
So remind me, who needs to catch up with who again?
