So did this problem base just appear from nowhere? In an ideal world the laying of the track, from base to shale surface, would have been under the control of speedway personnel. As that wasn't possible then they should have been constantly monitoring the process to advise where necessary. The project is currently a laughing stock and the promotion and PR has been abysmal. At such time as the problems are solved then that will become, and hopefully remain, a thing of the past.
