just wondering as the c stock, 1972 and 1967 stock were all done before the a stock, when i would have thought the a stock would be on the list to go first due to its age well above the other stocks mentioned
on another note, i have always wondered why the 1973 stock got dmi's on the inside of the train yet the 1992 stock was delivered without any at all! Will they receive any in the future or is a massive refurbishment on the list?

I think it was something to do with the fact that the C stock were in an appaling state, and weren't really suited to their jobs at the time (Transverse seats on the circle), and had been run ragged. Likewise the 72TS and 67TS were being run fairly intensively. However the A stock had a rather leisurely life, with quite a large number of units not being used at some point. Someone will come along with the numbers shortly no doubt. As for the others, it may be that when the 92TS were being specified, the DMIs weren't made necessary, but for the 73TS refurb, they were specified. I know that the 92TS were going to have a primitive 'moving map' installed, but for whatever reason (cost I think) it was cancelled.

The 73TS were specified in the mid 90s (94? 95?) by which point the DDA was in progress and, thus, standards for display equipment were known. The 92TS would have been specified by - what - 1990 at the latest, and probably earlier considering its background with the 86TS - such requirements for visual information a) probably didn't exist and b) would have been far more technically challenging.

I have heard that the 92 stock is having DMI,s retro fitted as part of their upgrade in the near future.

From 2017 the 1992 stock will undergo yet another refresh so that it can start to be made compliant with the Rail Vehicle Accessibility Regulations (RVAR) 2010 in time for 2020. This will include internal DMIs and dedicated wheelchair bays. There might also be scope for modifications to the lighting units as well as general repairs.
The main reason why the 1992 stock never initially received such screens was on the grounds of costs. Obviously by 1996, it must have been deemed more cost-effective for the 1973 stock to receive them, although they weren't utilised to their full potential until a decade later (originally they would just scroll the destination as seen in the following clip:

The 92TS would have been specified by - what - 1990 at the latest, and probably earlier considering its background with the 86TS - such requirements for visual information a) probably didn't exist and b) would have been far more technically challenging. Remember that none of these systems came in to fashion until the mid-1990s. The first mainline trains to receive this equipment were the class 165s and 465s, designed very early 1990s, both of which had very basic systems which at the time could only give lists of calling points. The first mainline trains to be able to announce the actual location were the class 365s (introduced around 1997-1998), and this system was relatively primative in that it could only cope with a limited number of stopping patterns and destinations. Meanwhile on LUL, apart from experimental systems on the 1986 stock, only by the mid-1990s did in-car displays become the norm, firstly on the 1996 stock. If I recall correctly, the 96 and 95 stocks and also the refurbished 73 stock were all designed by the same designers, which might have been a reason why they all got this feature. I would suggest that the disability legislation followed what was being seen appearing on trains, rather than being the driving force. Remember that the A stock refurbishment design was finalised around the same time as the 96 stock design, and no form of information provision was ever provided on these trains. |
