It recognised the issue that there is a dependency on getting the tunnelling away to open Old Oak Common and said that, ultimately, it might seek funds to compensate the Government for that tunnelling from the private sector as part of the wider development – “If there is a cash flow issue, the taxpayer will probably have to substitute for that in the short term.”50 The Department told us that “The attractiveness of Euston and the high-speed station at Euston is only going to be realised if you have the approach into Old Oak Common. That is understood.”51
