The latter I believe is the plan. At least some of the platforms in question would be very difficult to extend anyway.Given 5 car trains are planned to run between Manchester and Swansea, would it not be worthwhile to extend those 4 car platforms anyway? (I realise that's a more long term task than getting the Mk4's in)
Or are the Civities going to have ASDO which is more fondly looked on than standard SDP
Incidentally, many stations have already been fitted with stop boards for the MKIV sets - at least some of which are in positions that would not work if the sets were extended.
Indeed. I suspect the original 3 sets will enter service in their current 4 car formation long before anything from these extra sets do (if indeed they're even coming in the first place, none of this is has been confirmed yet!).They can get them as soon as they like, the carriages will still need a long list of work doing to them before being compatible with a 67 and ready to work. Maybe summer next year...
