I always record the 6pm news and keep it for a day, and Ronski is right, the crash was mentioned.
After 90 seconds of 'boom-de-da-boom' headlines drumbeat for Trump, that tram crash got a drumbeat lasting about 8 seconds, slightly less than the drumbeat for the sports news that followed.
I don't always give the drumbeat my undivided attention, which is arguably own fault for missing it. But I then had to sit through 35 minutes of the US election, before just over 2 mins of that tram crash, followed by about the same (2 mins) of weather, then back to the election again.
I don't think I am entirely to blame for having completely missed the story about the London tram crash which, IMHO, ought to have been a pretty big story.
