12s are not currently permitted due to SDO issues at Newport - work is underway to resolve this but it wasn’t going to be completed, validated etc in time for 6 nations.
There are Cardiff events later in the year where 12 cars are intended to be used; and the works to enable this are on track to be completed for then.
Presently the post-events strategy is to use 387s on what traditionally were TfW-operated Newport shuttles, to free up DMUs for Valleys, Marches etc. IETs still handle the bulk of post-match Bristol/London traffic which isn’t necessarily the primary destinations of event goers.
6 nations shuttles will show how well this goes, and whether that new strategy works.
