Northern Trains has released a tender for 450 new units. Which ones do we reckon are being replaced?

I noticed Phase 1 is for EMUs, so assumedly the 319s and 323s

The 150s have to be first diesels for the chop, along with the 155s and 156s. I'll be sad to see the 156s go, they're the epitome of a DMU in my mind.

I wonder if the 158s will be removed. I hope not
