Dear Mr Ketabchi

Our company, Newt International of the UK, has performed many examinations of railway wheel tread surfaces using the Lizard FGI (Field Gradient Imaging) system. Using this advanced electromagnetic method we can interrogate the surface of the tread to identify (amongst other issues such as cracking, spalls, stick slip events) the running band or work hardened part of the tread as well as the profile changes. We have performed such measurements on passenger fleets and for freight vehicles with fantastic results, ensuring a much greater level of information from the tyre surface than could ever be gleaned from visual and dimensional measurements alone.

If you would like more information please contact me or visit www.lizard.co.uk for further information. I hope that this has helped.

Best regards

Paul Bentley

Dear Mr Ketabchi

Thank you for your continued interest in the Lizard technology. I have had interest from companies in Iran recently but unfortunately have been informed by the UK Department for Business, Enterprise & Regulatory Reform (formerly DTI) that it will be incredibly difficult to do business between our countries in the current political situation. This is extremely unfortunate. If this information is incorrect or somebody believes there is a solution to this problem I would be very interested to hear from them.

Best regards

Paul Bentley
