A few months ago Hammersmith & Fulham council publicly complained that the cost of Imperial Wharf station had risen to £6.5m. They were looking to get the price lowered and promised they were working on a funding plan. They've now published the next instalment:
Hammersmith & Fulham Council, working with Kensington & Chelsea Council, Tfl and developers St.George, had a funding package agreed in the summer that would have meant the station got a green light but just as progress looked likely Network Rail’s construction and project management fees increased. The total cost of building the station is now £7.93 million.They're asking for Network Rail themselves to cover the increase.
