The Crossrail Bill passed its second reading in the Commons this summer (Planning, 22 July, p1) and is due to be considered by a select committee.
This week shadow transport minister John Hayes criticised the government's progress on bringing forward the east-west route.
In a Commons debate Hayes complained: "The government's record is appalling. Dozens of projects have been cancelled or postponed and many commuter services into London are at 105 per cent capacity during the rush hour."
But transport secretary Alistair Darling said that the bill passing its second reading is clear evidence of the government's intentions to build the railway.
