This thread (https://www.railforums.co.uk/threads/ireland-and-northern-ireland-unit-and-carriage-numbers.137696/) is locked, hence a new thread in the same sub-forum. This is a rare event; pdeaves talking about numbers! There seems to have been some 29000 units altered from their 'proper' formation. Ordinarily, unit 29001 would be vehicles 29101, 29201, 29301 and 29401, then sequential for other units. The cab fronts carry the vehicle number (29101 at one end, 29401 at the other). Last weekend (15 June) I saw an 8-car set led by 29129. Expecting something different at the rear, I was surprised to see 29429, i.e. the number that 'should' be in the middle of the set. Others in my party confirmed that I didn't mistake a 4-car for an 8-car and that what we saw was 'wrong'. Can anyone advise what the formations are now, please?
