Here is the blurb.
Eurostar needs you!
Help us prepare for the big day and get free travel on Eurostar
If you interested in participating as a passenger in one of these test days and to be one of the first to see the new stations you just need to register your details and well let you know where and when to come along.
You will be acting as a typical traveller picking up tickets, going through check-in, security and passport control, boarding and departure and finally arrival up to 3 times in one day.
Testing will take place on the following dates:
Tuesday 30th October,
Wednesday 31st October,
Thursday 1st November,
Wednesday 7th November and
Thursday 8th November.
You will only need to be available for one of these days. You will need to arrive at St Pancras some time between 08:30 and 11:30 and will be required for somewhere between 5 and 6 hours.
Although trains will not be going through Eurotunnel (they will either turn round outside St Pancras International or go to and return from Ebbsfleet International), all participants will need a passport/national ID card (valid for international travel).
Refreshments will be provided during the day, including lunch, and travel expenses will be reimbursed up to a limit of £25.
As well as the chance to take part in this unique phase of testing, participants will also get a voucher to be redeemed for a free standard class return ticket to Paris, Lille or Brussels on HS1 (terms and conditions will apply).
