Take advantage of the wind to stop, why can’t the train suddenly brake? : Okezone techno
ACCIDENT KA 112 Brantas, which hit a tow truck and exploded, has become a topic of conversation on social media. The lorry which allegedly broke down in the middle of the crossing was seen to explode shortly after being hit by the train.
Fortunately, there were no fatalities in the crash, but there are many lessons to be learned from the crash. Sure, trains can’t brake suddenly, but this common knowledge is apparently not known to everyone.
PT KAI responded to this through one of his tweets on his official Twitter account, @KAI121. He explained a number of factors and reasons why trains cannot make sudden stops.
“Many people are unaware that trains cannot stop or brake suddenly. This is evident from the comments of netizens who asked why the driver didn’t apply the brakes when he learned that a truck was stuck at a level crossing,” he said. wrote PT KAI on Twitter.
In his upload, KAI explained that trains cannot make sudden stops due to the length of the circuit and its heavy weight. The longer and heavier the series of trains, the greater the distance required to actually stop.
It was also explained that in Indonesia the average passenger train consists of 8-12 cars weighing up to 600 tons. This weight does not include the weight of passengers and their luggage. Under these conditions, the train requires a lot of energy to stop the circuit.
Even though trains are currently equipped with emergency brakes, they cannot make a series of stops immediately. But it increases the air pressure and energy so the train can stop faster.
“So even if the driver sees someone crashing into the track, it will usually be too late to brake,” KAI wrote in a Twitter post.
Furthermore, there are also several factors that influence braking distances such as speed, gradient, percentage of braking force, type of train, brake type and weather conditions.
