A new Tube map has been released to mark one year until the Elizabeth line is launched. The inclusion of the purple line is one of the most significant updates to the map in decades. In December 2018 the line will operate in three sections from Heathrow Airport in the west to Abbey Wood and Shenfield in the east. This will involve 15 trains per hour running through new tunnels built under the capital in the £14.8 billion Crossrail project. | ITV London
