So what is actually confirmed being transferred from the North West to the North East and whats confirmed transferred from the North East to the North West.

Also, this transfer of Pulsars to replace similar aged Temsas ain't gonna last that long is it. I would imagine there is a bigger picture with this move. I would personally say, keep the Temsas going until there is no spare parts from others to keep them going. May aswell get more value for money out of them. Then have these North West Pulsars spare.
