A Transport for London spokesman said: "London Underground (LU) has
examined the possibility of extending the Victoria line to
Northumberland Park, and this has proved not to be a viable option. The
only viable location for a station at Northumberland Park is to the east
of the WAGN tracks, which would mean that either large crowds would be
using the level crossing or existing narrow footbridge, or that a new
footbridge would have to be constructed at great expense.

How great an expense could a new footbridge possibly be? Are TfL assuming
they'd be paying for it? How much dough could be extracted from Spurs? If
it meant they could stay where they were rather than moving to a whole new
site, surely they'd be willing to pay quite a bit for it?

How would a Northumberland Park spur (excuse the pun) affect Vic
operations? The junction is between Seven Sisters and Tottenham Hale,
right? Would this mean diverting trains away from Tottenham and
Walthamstow? Or are there enough Seven Sisters reversers to cover the
branch, in terms of paths? Could you run Seven Sisters - Northumberland
Park shuttles? Either way, you'd need more trains, right? Is the junction
flat or graded? Are there two tubes to the depot, or one?
