There is a software incompatibility between the 800`s and 802`s apparently as the 802`s weren`t part of the original Dft plans for the west and east. Considering they are identical in almost every way and 802`s which were intended for use on the West of England lines are regularly used on the South Wales routes it seems pretty daft. Still, Jimm and his gallant band of IET defenders will no doubt be along shortly to tell me the error of my ways.
Is it even worth bothering, as it wouldn't make a blind bit of difference no matter what I or anyone else says in response to some of the things that get posted here, would it?
I expect Bletchelyite will still be doing his sales pitch in 10 years' time for Grammer seats to be fitted instead of any and every other type of seat installed in any and every type of rolling stock running in Britain - no matter how many times other people say they have no issues with Fainsa seats, or that they hate Grammers.
I doubt that not being able to couple an 800 to an 802 in regular service is giving anyone at GWR or Hitachi sleepless nights. Why should it, when there is no obvious need to operate them in this way and the acceleration settings are different? They can still make a physical connection to rescue each other if required, which is probably a rather more important consideration.
I've lost count of the number of times that Clarence Yard has tried to get over the message that the 802 fleet was never intended to be dedicated 24/7 to the West Country services and that the orders were also intended to address issues that GWR had identified with matching the DfT's initial order for IETs with the December 2018 - now 2019 - timetable plan, along with the subsequent changes in requirements resulting from things like the delay to Oxford electrification.
