Narita Express 253 Series Formations Question

[1954G]

Quick question about the 253系 NEX.  

 

I'm aware that the 253系 operated as a 3-car train, a 3+3 (early to mid 1990s), a 6-car train, and a 6+3. 

 

But during its years of service as the Narita Express, was a 253系 3+3+3 formation ever formed?  

 

Wikipedia (by way of Google Translate) seems to think so:

 

 

2009年4月時点で6両編成と3両編成が存在し、編成は下表のとおりである。E259系の投入前は3連+3連、3連+3連+3連、3連+3連+6連という編成で運行されていたが、E259系の投入後は6両編成のみの運用となり、6連単独または6連+6連の形で運行された。

 

But I haven't been able to find any pictures or videos of the Narita Express organized this way. 

 

Can anyone shed light on this?  Thanks.

They were used as 9 car sets while the 3+3=6 conversions were under way, so for a limited time only.

This picture has 9 cars and i can count 3 red fronts facing the camera and 3 pantos on top:

(you can also make out the front skirts)

Which is probably why I couldn't find any video of a 3+3+3 9-car set.  Of course, I did find videos of this formation...on someone's n-gauge layout.  Which wasn't enough to answer my question!   :) 

 

Thanks for the help.
