 Either the conductor or the driver (it is not known which) changed the lights from white to red to warn oncoming trains of the obstruction but no other action was taken.Meanwhile, another Super-Sprinter train forming the 1745 Carlisle to Leeds service (headcode 2H92) had set off from Kirkby Stephen railway station around five miles to the north.About a quarter of a mile before the derailed train, the driver saw its red lights and made an emergency brake application, but there was no chance of stopping before impacting the derailment.
