Bakerloo Line extension - not just a pipe dream?

As discussed here, the idea of extending the Bakerloo line beyond Elephant & Castle to this part of South East London is one that has been kicking around for a long time.

However, London Reconnections claims to have good sources within London Underground, who suggest that serious plans may now be taking shape:

"London Underground undertook a strategic investigation into the possibility of extending the Bakerloo Line back in 2007... It is believed that a southern extension to the line was marked out as a major recommendation in the South London Corridor section of TfL’s Underground: 2025 report, produced in the same year, which concluded that of all the options in the area (Victoria Bakerloo and Northern), an extended Bakerloo would yield the most benefit.

"Sources indicate that TfL’s report also looked to establish what route an extension would likely take... and that, broadly speaking, it recommended three possible options, with London Underground’s own in-depth assessment concurring with TfL’s findings."

Of the three options outlined, two would directly benefit this area:

Option 1: Via Honor Oak to Catford Bridge
Option 2: Via Herne Hill
Option 3: Via New Cross to Lewisham (and then potentially to Ladywell and Catford Bridge)

Reconnections claims that options 1 and 3 are the preferred routes, currently.

While this project remains a distant prospect, it seems very likely that the next tube extenstion for London will be coming this way.
With thanks to Richard Elliot for spotting this.
