As far as the proposed Crossrail 2 link is concerned, the Treasury expects a budget of almost £8bn for emergency situations for this scheme that is estimated to cost around £12bn. Strict and able guidance is required to reduce actions and incidents that could lead to uncertainty and cost inflation on projects. Detailed design and precise cost estimation can minimize the cost of Crossrail 2 as it is in its initial stage.
Decisive political support is required to continue with the scheme of Crossrail 2 to ensure that designers and contractors can work on minimizing its risks and overall cost.
The London rail capacity is expected to be full at the seams when Crossrail 2 opens in the latter part of this decade. Only then the ordinary Londoners may find the advantage of having its building sites on their doorsteps.
