There will also be a bogie monitoring system designed to continually monitor the condition of the critical bogie components.\u00a0<\/p>\n
A bogie is the undercarriage of a train, which houses the suspension systems, axles, gearboxes and wheels.<\/p>\n
The monitoring system tracks parameters such as wheel wear, axle load, temperature, vibration, alignment, and structural integrity.<\/p>\n
This means that early signs of degradation, such as through overheating, can be detected before a fault occurs.\u00a0<\/p>\n
\u201cThis system minimises unexpected downtime, keeps trains operating efficiently, and ensures a stable and comfortable ride for commuters,\u201d said SMRT.\u00a0<\/p>\n
There are currently no on-board systems to monitor and feedback the condition of critical bogie components in real time. Issues with the bogies that could result in bumpier rides could instead be detected upon feedback from commuters.\u00a0<\/p>\n
A bogie with an undetected fault can result in costly disruptions.\u00a0<\/p>\n
In September last year, a six-day train disruption on the East-West Line occurred when a defective axle box on a first-generation KHI train dropped onto the tracks, causing a bogie to come off the running rail and damage the tracks.\u00a0<\/p>\n
Train doors will also be monitored in real time. At present, a door fault only indicates which cabin the defective door is located in, requiring maintenance staff to inspect multiple sets of doors.\u00a0<\/p>\n
The new system will pinpoint the exact door with a potential fault, speeding up repairs.<\/p>\n<\/div>\n
