The Queen, the Duke of Edinburgh and the Duchess of Cambridge are going underground, to celebrate the 150th birthday of the tube.
The Royal party will be greeted at Baker Street by the Commissioner of Transport for London, Sir Peter Hendy, and the Managing Director of London Underground Mike Brown.
They'll meet maintenance and train staff and will view a restored 1892 underground coach. They'll then walk through a new S7 train where the queen will unveil a plaque, naming the train Queen Elizabeth II.
Transport for London has backed the plan to build a second Crossrail link across London. The organisation says a new link is needed because of population growth and the extra passengers using Euston after the High Speed Two rail link is finished to Euston.
But TfL's Managing Director for Planning, Michele Dix, says construction on Crossrail 2 will only start after the first Crossrail link is finished in 2018.
Val Shawcross, the London Assembly Labour Transport spokesperson, responded to the proposal to build a new North-South Crossrail link:
"This is critical to continue London’s economic success. London's business leaders and politicians from all parties are supportive of these plans in principle. We all recognise the need to carry on expanding London's public transport network well into the 21st century.”
Ten thousand tube workers are in line for an £850 Olympic bonus as part of the latest offer to "buy" their co-operation. London Underground has already struck a deal which gives 3,400 drivers up to £1,000 for working during the Olympics and paralympics.
Now unions and managers are negotiating a separate agreement for station staff and maintenance workers. For every shift worked, up to a maxium of 20 days, staff would get £20. On top of that they could be entitled to a £100 Customer Service Satisfaction Bonus.
An additional payment of £350 woud be made if they agree to flexible rostering during the games.The unions are considering the offer.
