Since when should I have to 'dig it out'. If I make reference to documents myself, I will always try to give a link - lots of other posters do too - and if the point is buried in an extremely lengthy file, say where to find it. That is, like I said, common courtesy. The original poster didn't bother.
Even then, the Northern franchise agreement just refers to sets from different leasing companies, not where those sets are currently being used.
You appear to know all this detail without having to give it a moment's thought - but I, and I suspect rather a lot of other people, don't, so please don't keep on lecturing us about things that aren't always as obvious as you seem to think.
Like I said this seems to be discussed every few weeks. It's long been established Northern have agreed to take on all the 150s belonging to Angel Trains - the ones which GWR had planned to release will be taken on once GWR have finished with them, with the last few once the current lease expires (in 2019.)
You wanted to know which page in the Northern franchise agreement but there's 3 things you need to look at to confirm the above is the current plan:
1. The future fleet list in the Northern franchise agreement
2. The current fleet list in the GWR franchise agreement
3. A source saying how many 150s Angel own
It's not practical to reference everything in every forum post.
I told you the easiest way of finding fleet lists in the franchise agreement if you know which class of trains the operator has or is taking on. (Page numbers can cause confusion due to the printed page numbers often being different to the pdf page numbers.)
Nor does what is written in that document prove what will happen and when one way or the other.
While I agree that something in a franchise agreement could change if both the operator and DfT sign off the change, don't forget you were using a RAIL article (RAIL articles not always being the most factually accurate) from a couple of years ago to try and argue that another poster was wrong.
You also brought up the old wives tale of a Green train means it's guaranteed to stay with GWR even after the current franchise. Where's the reference for that? Wasn't there a story about First Group being angry with a rail magazine for wrongly claiming the green GWR branding was DfT's idea when it was actually First's idea?
I'm pretty sure there's an agreement that the
current GWR franchise can retain units for an additional 26 weeks (even if a lease has been agreed with another operator) if the replacement trains/wiring is delayed.
If you think that those rolling stock swap-arounds, and the introduction of expensive-to-run loco-hauled services, happened without the explicit say-so of the DfT, you must be dreaming.
You're missing the point - they happened because DfT didn't want to interfere with Porterbrook's decision to lease the 170s to Chiltern so helped TPE by looking for whatever option they could find for TPE to not lose capacity but still forfeit the 170s.
FGW didn't get the 150/0s, the two orphaned 150/2 coaches and five Class 180s back in 2012 until lengthy negotiations resulted in a variation to the then franchise agreement - which was quite a while after the coalition Government was formed.
That doesn't have any relevance to the point I was making. They were off-lease units and the DfT sign off would have been because it involved changing the franchise agreement, from the previously agreed deal. Presumably the additional leasing costs is what needed the DfT sign off.
No more stupid than removing Class 150s from GWR when it still has a use for them. Drivers can be trained on different stock. GWR drivers operating routes radiating from Bristol will all have to learn Turbos. More Northern drivers could learn 153s - or just carry on driving Pacers for longer.
I agree that removing units prematurely from a franchise isn't a good idea but if it's going to happen is there any need to make things even more complicated? Northern crews will be learning 170s, 195s and 331s, as well as Northern having to sort out route clearance for those traction types.
Not that any of this really has anything to do with GWR livery
Agreed the only point relevant to the GWR livery is unreferenced and seems to be an old wives tale!
