Campaing for suppressing level crossings

I was this morning at North Sheen's level crossing, waiting 12 minutes behind the barrier (missed my train as the entry from the station is on the other side) and pondering about the dangers of the level crossing: this week-end two 14-year-old girls got killed in Elsenham, Essex as they crossed to catch their train.

(see coverage on BBC and other sources)

And while I was raging against this level crossing, a schoolboy (probably going to Christ's School) jumped the barrier and crossed the tracks. He probably did not read the news...

Bob Crow from the RMTU (not my usual source but...) is quoted here saying that the cost of an underpass or a bridge is around £1m. Are two girls' lives not worth it?
