A signal passed at danger (SPAD), known in the United States as a stop signal overrun and in Canada as passing a stop signal, is an event on a railway where a train passes a stop signal without authority. In the United States and Canada, this may be known colloquially as running a red, though this idiom principally refers to automobiles passing red traffic signals.

The Cowan rail accident occurred at 7:20pm on 6 May 1990 when the 3801 Limited special steam passenger train returning from the Morpeth Jazz Festival was struck in the rear by the following CityRail inter-urban passenger service. The steam train had stalled while attempting to climb the steep gradient from the Hawkesbury River to Cowan, New South Wales, and it was found that sand applied to the rails to regain traction had interfered with the signals and given the following train a false clear indication.
A wrong-side failure describes a failure condition in a piece of railway signalling equipment that results in an unsafe state. A typical example would be a signal showing a 'proceed' aspect when it should be showing a 'stop' or 'danger' aspect, resulting in a "false clear".

The Ballymacarrett rail crash occurred on 10 January 1945 at 7:50am in the Ballymacarrett area of Belfast, County Down, Northern Ireland on the Belfast to Bangor Line of the Belfast and County Down Railway, when a train led by a heavy autotrain driving trailer ran into the back of a stopped passenger train consisting of lightweight wooden coaches. 22 died with 27 injured. It was the worst crash in Northern Ireland since 1889. The cause was found to be carelessness of the driver of the autotrain who was running too fast for conditions. Fog, unsafe railway rules, and possible distraction from passengers all may have contributed to the accident. Old lightweight rolling stock contributed to the great number of injuries and deaths. The accident led to the demise of the railway company which was nationalised three years later.
On 3 February 2003, a Comeng electric multiple unit train rolled away from Broadmeadows station in Melbourne, Australia, before it ran for nearly 17 kilometres (11 mi) out of control without a driver and eventually crashed into another train about to depart Spencer Street station. Train controllers attempted several times to stop or redirect the train, but were limited in their ability to intervene, instead being forced to alter the route of other trains to avert a more serious collision. Eleven people on board the stationary train were injured; authorities did not know until after the crash if any passengers were on board the runaway. An investigation identified driver error as the cause of the accident, but the runaway event prompted significant debate about the role of government authorities and private operators in ensuring safety and reliability on the Melbourne rail network.
On the evening of 26 December 1962, cold weather and snow in and around Crewe had caused points to become frozen and trains were being detained at signals. About midway between Winsford and Crewe, the 13:30 Glasgow Central to London Euston Mid-Day Scot, hauled by an English Electric type 4 diesel, D215, with 13 coaches and 500 passengers, was stopped at a signal but the driver found the telephone to Coppenhall Junction, the next signal box ahead, out of order. Seeing the next signal ahead he decided to proceed down towards it and use the telephone there, but too fast. In the darkness he failed to notice the 16:45 express from Liverpool Lime Street to Birmingham New Street, hauled by an electric locomotive with eight coaches with 300 passengers, standing on the line ahead and collided with it at about 20 mph (32 km/h).

The wreckage of the goods train was then hit by an express train heading north from London King's Cross, killing ten people and seriously wounding 18 others.
