Hello Peter,

Gone through your review comments for this year's paper and have some questions.

Thank you and Regards

My error- platform tracks of course are DD or DE.
I could blame it on being distracted by having actually to do some commisioning relevant work on the shift, I could claim it was deliberate ploy to see whether you actually reading my replies, I could claim as the French do "that an error slipped itself in", or I could just admit it!
