Heathrow rail services resume after trackside fire causes weekend disruption

Train services to Heathrow Airport have resumed after a trackside fire caused severe delays and cancellations on Saturday, with no trains running between central London and the airport. The incident disrupted travel for thousands of passengers, though the cause of the fire and the full extent of the impact remain unclear. The quick restoration of service suggests limited long-term infrastructure damage, but the event highlights the vulnerability of key transport links.
