Recently, some netizens posted a video saying that Wuhu Light Rail Line 1 was "sliding". video shows,When the light rail train set passed a climbing line, the train gradually stopped moving forward, and then slid back down the slope, but did not continue to slide.In this regard,Track customer service responded that bad weather conditions may have a certain impact on operations, and the specific reasons still need to be investigated by relevant departments.
According to previous reports, some subway operation technicians said that sliding is a common fault during the operation of subways and light rails.
If the adhesion between the wheels and rails is less than the friction required for traction or braking, train sliding will occur.
The probability of idling is higher during rainy and snowy weather in winter, especially when the rainy and snowy weather has just begun or when there is continuous snowfall.Because the rail surface is prone to ice at this time, the adhesion between the wheel and rail is minimal.
At present, after the meteorological department releases snowfall intensity forecasts for specific periods, subway and light rail operating departments generally take targeted measures, such as reducing driving speeds or directly suspending operations when snowfall intensity is heavy.
