I have just read in the Swiss News that another collision has taken place in Thun during the night (17th May) and three railway workers have sadly lost their lives. There is a lot of modernisation work taking place in the area and it appears that two works trains have collided. Although in the same area I don't think that this latest accident is linked to the previous one.
