Further to your answer 3461/2011. While I am pleased that the Northern line upgrade will deliver faster and more frequent journey times, I do not understand your reasoning for not replacing the current trains with driverless rolling stock. In your answer you mention the Central line as one being considered for driverless technology through new rolling stock, but say the situation does not apply for the Northern line because its fleet of trains are relatively new. Given that the Central and Northern lines' current rolling stock were introduced in 1992 and 1995 respectively surely the latter's trains will also soon qualify for replacement too.

Written answer received on 21 December 2011:

I am not suggesting that Northern line trains will not be replaced. Procurement of new fleets for deep Tube lines does however need to be prioritised and sequenced to provide the best value for money for Londoners and protect reliability on the Tube.

We envisage new trains being introduced on the oldest deep Tube fleets - the Bakerloo and Piccadilly lines - in the early to mid 2020s. The Central line would be next in the late 2020s, followed by as you point out, the Northern line fleet in the following decade.
