From what I have heard from friends at work today the notice simply says that the unions and the company have agreed on all the points for single fleet and the start date is still expected to be October 2006. I assume there will be a more indepth announcement soon.
As for training at LGW, it is held at Hangar 6 on the perimiter road. You will get details of how to find it in your start pack. There is a small canteen at hangar 6, you may want to bring your own food. Sometimes the queues are long and it's meant to be primarily for our engineers etc, I used to feel sorry for making the guys wait so long sometimes!
