Investigation Reveals Brake Failure in Fatal Welsh Train Crash

A tragic train collision in mid Wales has drawn attention to serious safety concerns after it was revealed that the braking system of one of the trains failed. This incident, which occurred near Llanbrynmair on October 21, resulted in the death of 66-year-old David Tudor Evans and left several others injured.

Collision Details

The crash involved two trains: one traveling from Shrewsbury to Aberystwyth and another from Machynlleth to Shrewsbury. Initial reports indicated that the Shrewsbury-bound train struck a stationary train.

The Rail Accidents Investigation Branch (RAIB) has since reported that the 1J25 service suffered from a blocked wheel-sliding safety system, which is critical for stopping the train effectively. Investigators discovered that an automated sanding system, designed to enhance wheel traction during braking, had malfunctioned due to blocked hoses that were unable to discharge sand.

The RAIB’s preliminary analysis indicated that the Shrewsbury-bound train was traveling between 15 mph (24 km/h) and 24 mph (39 km/h) at the time of impact, while the opposing train was moving at approximately 6 mph (10 km/h).

Though both trains did not derail, significant damage occurred at their leading ends. The investigation continues, particularly regarding the speed and conditions leading up to the collision.

Safety Systems Under Scrutiny

Both trains were equipped with wheel slide protection systems, akin to anti-lock brakes in vehicles. The Cambrian line also utilizes the European Rail Traffic Management System, which provides critical signaling data directly to trains.

During their investigation, RAIB noted that the westbound train was supposed to stop in a loop at Talerddig to allow eastbound traffic to pass. However, data from the on-train data recorder revealed a series of brake applications leading up to the crash, including a service brake followed by an emergency brake demand just before impact.

Following Mr. Evans’s death, British Transport Police faced criticism for their handling of support for his family. They later issued an apology for any distress caused during this difficult period.

Transport for Wales and Network Rail emphasized their commitment to cooperating with ongoing investigations and have implemented enhanced safety checks on trains and tracks as they prepare for the reopening of services on the Cambrian line later this month.

As this investigation unfolds, it underscores the urgent need for thorough safety protocols within railway systems across the UK. The outcome will likely influence future operational practices and regulatory measures aimed at preventing similar tragedies.
