I've heard some talk of ATO start buttons on the 1995 stock being moved from their current de-centralised positions with each one on the two door control panels either side of the TOD's (Train Operators Display) to a position where they are next to each other as seen on other ATO enabled stock on LU.
Are they going to follow a similar layout to the 1996 stock or does other features of the 95's necessitate a differing design?
Thanks in advance,
G.Arrow

"Heard some talk" = read a driver's Twitter, per chance?
They are indeed moving to match the position of the 1996 stock.

A couple of questions:
Why was the location of the buttons designed differently on the 95 stock?
Have there been documented issues with the layout?

Was told of this when conversing with some staff at Golders Green + a facebook group mentioned something along those lines, I think there was some grumblings on twitter per say about the strain the current position was on some T/OP's backs, but nothing about mods as far as I can remember. |

The 95 TS were not built or planned for ATO whereas the 96 TS were built with a provisional Westinghouse ATO designed system which included ATO buttons, As the Train Management systems are completely different the position of all the cab button functions are different on the two stocks, so 95 TS conversion was done with blank buttons and redundant button positions used, after service use it appears there are a few issues, as the system has bedded in other options to reposition the buttons has been explored and to be implemented.

I didn't think that was true? They were delivered with two ATO start buttons in that very position were they not, along with the Westinghouse speedo with target speed all ready to go. The Northern was due to get new signalling a lot lot earlier was it not? |

It’s the removal of redundant buttons and visuals that has allowed the buttons to be moved, one of which is the “tripcock delay” visual. |

The old location for the buttons was awful - requiring train operators to heavily lean forward as well as having to reach out with both arms. I think few will miss the old location - this change has been talked about for some time now. As an aside, there’s already been a delay when someone took charge of a modified train and couldn’t find the start buttons... |

There were two separate engineering teams in LU for Jubilee 96TS and Northern 95TS in the original design phases. I was in one of them and I'm sure both undertook ergonomic assessments. It was curious then and now how many small and not so small differences they ended up implementing in the cab controls.
The Jubilee design definitely assumed a Westinghouse ATC as the contract for that ran alongside, but gradually later, until modified/cancelled in the late 90s to get the Jubilee line Extension opened with trainstop signalling.
I seem to recall that the Northern line train was engineered assuming the same ATC interface, because both needed similar mods to take the current Thales TBTC system they now have.
