What accident?

"Does anyone else notice how B&M trains "fly" through the break run?"
I would also testify that certain ride manuals at a certain park that I swear I've never seen say they apply pressure to certain B&M rides at the mid-course based upon the speed of the ride, which varies based on wind, weight of a loaded train, etc., and it is computerized. The secondary purpose is to keep the optimal interval right.
"Supposing something goes wrong and a train has to stop temporarily in these block brakes somewhere halfway round the circuit. When the block ahead clears, it is necessary to open the block brakes, and the train must coast from a standing start safely around the rest of the circuit without stalling. Now, if the circuit is designed for a train to leave the block brakes from a standing start, it is therefore not designed for a train to leave the block brakes at full running speed, where it will belt round the rest of the circuit with an excess of kinetic energy. If the circuit is designed for the train to leave the block brakes at full running speed, the chances are that if it leaves them from a standing start it won't make the next hill, and will stall."
