A MINIATURE train crash that injured six people at Longleat Adventure Park last year was caused due to ‘weaknesses’ in maintenance and staff training, according to independent regulators.

One woman suffered a broken leg in the crash last August after two carriages overturned and was just one of a three incidents that involved carriages overturning.

The train derailed in 2011 and also in November 2014, just months after the most serious incident.

The Office of Rail and Road (ORR) found 'weaknesses in train operation safety management, specifically related to maintenance, staff training and competence'.

It added: “In response the company agreed to implement an action plan to improve their standards, and have subsequently made significant changes to their operating procedures.

“ORR’s inspectors are closely monitoring the operation of trains at Longleat to ensure safety is not compromised.”

Emergency services, including the air ambulance, were called to the park last August with many of the train’s 150 passengers helping those who had been injured.

A spokesperson for Longleat said: “The ORR has confirmed that their investigation into an incident involving the Longleat miniature train, last August, is now complete.

“The Longleat team have spent the past six months working closely with the ORR and expert external advisors to develop an advanced set of training and operating procedures for the Jungle Express train.

“We have looked at every aspect of the operation from the trains themselves and the track, to staffing and signalling.

“We have made a number of changes to the way that we operate the train and have revised and developed both the operating procedures and systems.

“We are satisfied that we operate to very high safety management standards and have in place a process for continuous monitoring and evaluation of the operation.”
