As I'm sure many of you know, the 'A' stock is (sadly) coming to the end of it's working life, and a replacement is needed. Eventually, all SSL stock (Sub-Surface Line) will need to be raplaced. This is where potential problems lie. LUL will be ordering only one type of stock, which will run on all SSLs in order to provide increased flexibility. This may sound good, but from a passenger's point of view, this is not necessarily the case. As the new trains will be of a standard design, interior wise as well as exterior, there will be no more high-backed seats which provide the level of comfort enjoyed by the Bucks. commuter on the Metropolitan Line. There will also be less seats, again, something which commuters will not be best pleased with, especially on the ELL, District and Metropolitan Lines.
