When the Victoria line was built, there were severe budget restrictions.
As a result, the station infrastructure standards were lower than on older lines and on later extension projects.
Examples of these lower standards include narrower than usual platforms and undecorated ceilings at Walthamstow Central, Blackhorse Road and Tottenham Hale.
This also affects lighting levels.
At most stations between the up and down escalators there is a concrete staircase where an additional escalator could be installed, but has not been fitted.
It can cause severe congestion at peak times.
This has been remedied at Brixton in 2004 and at Vauxhall in 2006 where an additional escalator has been installed in place of the fixed stairway.

In addition, there have been station closures for safety reasons, when both escalators have been unserviceable.
Over many years, heavy equipment has been installed in fenced-off sections at the ends of platforms owing to the lack of anywhere else to install them.
It is not clear from Transport for London's Five-Year Investment Programme whether these shortcomings are likely to be remedied.

The 1967 stock was replaced bit by bit from July 2009 as part of Transport for London's 5-year £10 billion redevelopment project.
The replacement for the line's 1967 tube stock is the 2009 tube stock built by Bombardier Transportation.
The first train was built in 2006.
Testing of the new trains began in 2008.
The main fleet began to be introduced in 2009 and went into main service in 2010.
The last of the 1967 stock trains ran on 30 June 2011, after which the whole service was provided by 2009 stock.

Supporters of Tottenham Hotspur (and the club itself) have campaigned for a surface station to be opened next to Northumberland Park Station, next to the line's depot.
This would provide an improvement in transport links, seen as essential if the club's wish to redevelop their ground and increase crowd capacity is to become a reality.
 The idea was looked into but Network Rail own the necessary land and need it for their own expansion plans.

When Crossrail 2 is built, it will lower the number of passengers on the Victoria line (there are too many at the moment).
It will offer an alternative route across Central London between Victoria and King's Cross St. Pancras.

For many years there have been proposals to extend southwards from Brixton one stop to Herne Hill.
Herne Hill is a railway station that can link passengers to Kent and other places.
The tube station would be on a large reversing loop with one platform.
This would remove a problem of having too many trains by getting rid if the need for trains to reverse at Brixton.
However, this would cost too much money for how little it would actually help passengers.
 Given that the line is very overcrowded, this is the only extension that could ever happen.
