The train driver did not set enough hand brakes (5 on the engines, one on the caboose, and one on the boxcar) to stop the 72-car crude oil train from rolling down the slope, the train rolled down the slope and derailed in a curve at high speed. Several tank cars burst and caught fire, killing 47 people [8] 2012 Ion Luca Caragiale village, Romania
"Sudden acceleration incidents" (SAI) are defined for the purpose of this report as unintended, unexpected, high-power accelerations from a stationary position or a very low initial speed accompanied by an apparent loss of braking effectiveness. In a typical scenario, the incident begins at the moment of shifting to "Drive" or "Reverse" from ...
The investigation conducted by the Canadian Transportation Safety Board revealed that the left brakes of Flight 420 had overheated during take-off, causing a fire inside the wheel-well which destroyed warning systems, as a result of which the crew was unaware of the severity of the fire, which subsequently ruptured hydraulic pipe-lines and ...
A pair of electronic loops are placed 50–450 metres on the approach side of the signal, energized when it is at danger. The distance between the loops determines the minimum speed at which the on board equipment will apply the train's emergency brake. When the train's TPWS receiver passes over the first loop a timer begins to count down.
Fire 159 Catastrophic and contained cargo fire in rear cargo deck lead to the separation of tail section, an in-flight break up and a high-speed dive into ocean 1988-04-28 Aloha Airlines Flight 243: Hawaii, United States Boeing 737: Improper adhesive bonding of fuselage lap joints 1 Corrosion and fatigue: 18 ft of roof separated from fuselage
Everyone survived, but due to structural damage the aircraft was written off. Lion Air Flight 538: 2004 Adisumarmo International Airport, Surakarta, Indonesia While landing in wet weather, the McDonnell Douglas MD-82 overran the runway due to hydroplaning and poor aircraft braking performance. After leaving the runway, the aircraft struck an ...
Use of one-step brake control permits high-density operations because there is no idle running time due to operation delay between brake release at the intermediate speed limit stage. Trains can run at the optimum speed with no need to start early deceleration because braking patterns can be created for any type of rolling stock based on data ...
Automatic train protection (ATP) is an advanced form of train stop which can regulate the speed of trains in situations other than at a signal set at danger. ATP can supervise speed restrictions and distance to danger points. It can also take into account individual train characteristics such as brake performance etc.
