Overheating Brakes Cause Elizabeth Line Train Evacuation at Paddington Station

Hundreds of passengers were forced to evacuate an Elizabeth line train at Paddington Station on Thursday evening after an overheating braking system filled carriages with acrid smoke, triggering a major emergency response. The incident occurred at approximately 6:20pm during peak rush hour, causing widespread disruption across the Crossrail route and leaving several passengers requiring hospital treatment for smoke inhalation and anxiety-related conditions.

Chaos Underground as Smoke Fills Carriages

Passengers on the westbound service from Liverpool Street described scenes of growing panic as a burning smell intensified and visible smoke began seeping into the rear carriages. The train's automated systems detected the brake overheating and brought the service to a controlled stop at Platform 13 at Paddington, where station staff initiated an emergency evacuation.

Commuter Priya Sharma, 29, a financial analyst from Ealing, said: "The smell started about two minutes before we reached Paddington. People were covering their faces with scarves and jackets. When the smoke became visible, there was genuine panic — people were pushing towards the doors. A woman near me was having a panic attack and a child was crying. It was terrifying because you don't know if it's going to get worse."

Emergency Services Respond in Force

London Fire Brigade dispatched three fire engines from Paddington, North Kensington, and Kensington stations, along with a hazardous materials unit. Approximately 740 passengers were evacuated from the nine-car train within 12 minutes using the platform exits. London Ambulance Service treated 23 people at the scene for minor smoke inhalation, and four passengers — including an elderly man with pre-existing respiratory conditions — were transported to St Mary's Hospital, Paddington, for observation.

"This was a swift and well-coordinated evacuation," said LFB Group Manager Andrew Blackwell. "Our crews identified the source as an overheating disc brake assembly on the fifth carriage and confirmed there was no active fire. The smoke was caused by brake dust and lubricant being heated to combustion temperature."

TfL Launches Urgent Investigation

Transport for London confirmed that the affected train, a Bombardier Class 345 Aventra unit, has been withdrawn from service for urgent inspection. "Safety is our absolute priority and we take any incident of this nature extremely seriously," said Howard Smith, TfL's Elizabeth Line Director. "We have launched an immediate investigation into the cause of the brake overheating and are conducting enhanced inspections of the braking systems across our entire Class 345 fleet as a precautionary measure."

The Rail Accident Investigation Branch has been notified and is considering whether to launch its own independent inquiry. Industry sources suggest the overheating may be linked to a known issue with brake calliper alignment that was identified in a manufacturer's technical bulletin earlier this year.

Disruption and Commuter Frustration

The incident caused severe disruption across the Elizabeth line for the remainder of the evening, with services suspended between Paddington and Ealing Broadway for three hours. Replacement bus services were provided but struggled to cope with the volume of displaced passengers. This marks the fourth significant operational incident on the Elizabeth line since its full opening, fuelling criticism that the flagship £18.9 billion project has not yet achieved the reliability standards expected of a modern railway.
